The Origin Of The O’ring The origins of the o’ring can be traced back to mid 19th century, when cast iron was chosen as a seal for steam engine cylinders. Results showed that an elastomeric material was required to aid sealing. As time ed, and engineers learned how to use rubber, the o’ring was truly invented. Today it has become the worlds most popular seal. Its simple shape, low space requirements, and easy fitting, combine with the large range of materials from which it can be made, to suit a wide variety of sealing applications. As the worlds most simple sealing device, we also find the o’ring to be the most abused. Simple, straight forward information about sizes and housing details, covering both the metric and imperial ranges, can be extremely difficult to find. Therefore, we have attempted to put it all together in a concise, easy to follow format.
Helpful Tips About O’rings •
When stating o’ring size, it is an international convention to specify the o’ring by its inside diameter (ID) x cross-section (CS).
•
All metric o’ring cross-sections are actual sizes.
•
All imperial o’ring cross-sections are nominal sizes. Example : a 1/8 nominal o’ring has an actual cross-section of 0.139”, not 0.125”.
•
The overall performance of an o’ring is directly related to the extrusion gap, groove dimensions, and surface finishes of the housing, as well as the appropriate selection of elastomer and compound.
•
Due to the vast range of metric o’ring sizes throughout the world, not all are readily available within Australia. Please confirm availability of your selected size in an appropriate elastomer and compound at the design stage.
•
Imperial o’rings are available in a wider range of elastomers and durometers ( hardness ) than are metric o’rings. This should be kept in mind at the design stage.
•
The two primary considerations when selecting an elastomer, are that it should be both compatible with the system fluid being used, and capable of operating within the required temperature range.

The Importance Of Cross-Section One of the greatest problems people experience when identifying o’rings, is getting an accurate measurement of the cross-section (CS). This task can be made a lot easier by ascertaining the origin of the machine to which it belongs. As each country works to a specific set of standard cross-sections, this information can be used to eliminate many potential selections. The following table shows common o’ring crosssections, and indicates those countries which use them.

Temp
General Service Applications
-40°C to 110°C
Nitrile is the most widely used elastomer in the seal industry. It has an excellent balance of desirable properties, with good resistance to mineral based hydraulic fluids, water, alcohol, and many other media. N9 is recommended for high pressure static applications.
V7 75 Durometer V9 90 Durometer
-35°C to 205°C
Viton has a resistance to a broader range of chemicals than any other elastomer. It has excellent mechanical properties, with good resistance to compression set and high temperatures. V9 is recommended for high pressure static applications.
C7 70 Durometer
-55°C to 140°C
Neoprene is unusual, in that it has moderate resistance to both mineral based hydraulic fluids and weather (ozone, sunlight, oxygen). It is also resistant to many refrigerants (freons, ammonia), and mild acids.
E7 70 Durometer
-55°C to 150°C
E.P.D.M. is resistant to water, steam, acids, alkalis, brake fluid, phosphate esters, and ketones, with excellent weathering properties. It has poor resistance to mineral based fluids.
-85°C to
Silicone has a very low physical strength and should be limited to static applications only. It is compatible with a wide range of fluids, as well as hot air.

Back-Up-Washers & The Effect Of Pressure Back-up-washers (BUW’s) are not in themselves a pressure seal. Specifically, they are a device to reduce o’ring extrusion, thereby enabling an o’ring to withstand much higher pressures with a given diametral clearance. The use of BUW’s allows extrusion gaps to be increased, permitting larger diametral clearances between the piston & bore or rod & gland at a given pressure, thus reducing machining costs. The figures below show the effect of increasing pressure on an o’ring, and that of introducing a BUW when pressure becomes too great for an o’ring by itself. The 3rd figure shows an o’ring at the extreme of its operating abilities. With the increase in pressure for figure 4, the o’ring is forced into the extrusion gap and destroyed. This problem can only be solved by reducing the diametral clearance (increasing machining costs), or the introduction of BUW’s as in figure 5.
B.U.W’s - Availability To Suit Standard Imperial O’rings Transeals stocks a comprehensive range of BUW’s to suit standard imperial o’rings (refer pages 8-13 for o’ring sizes) manufactured from 90 durometer nitrile (N9). These can be stretched during installation, enabling them to be fitted without being scarf cut. P.T.F.E BUW’s are also stocked in a wide selection of these sizes and can be manufactured in-house for the entire range. Being made from a harder material than the N9 BUW’s, they are suitable for more extreme applications. However, they do not stretch and must be either fitted into a 2 part housing, or scarf cut prior to fitting. B.U.W’s - Availability To Suit Standard Metric O’rings Unlike imperial o’ring standards, not all metric o’ring standards contain specifications for BUW’s. Therefore, it is not possible to get BUW’s to suit all metric o’rings. Transeals stocks metric BUW’s manufactured from P.T.F.E and HYTREL in a selected range of common sizes to suit G & P series o’rings (refer to page 14 for JIS B 2401:1967 o’ring sizes). Non-standard sizes can be manufactured in-house from P.T.F.E.
Extrusion Curves For 70 Duro O’rings & 90 Duro BUW’s Use these curves to determine maximum diametral clearance G.This value should always be kept to a minimum.

Standard Imperial X’Rings X’Rings are an elastomeric seal designed to replace o’rings in certain applications. They are basically square in cross-section, making spiral twist impossible, with concave sides to reduce the area. The frictional resistance for X’Rings is less than that of the corresponding o’ring for pressures up to 600 psi. X’Ring dimensions correspond with those for standard imperial o’rings, and as such can be fitted to existing o’ring grooves. Transeals stocks an extensive range of 80 durometer nitrile (N8) X’Rings in standard imperial sizes. Other elastomers and compounds are available only in selected sizes and limited quantities. our technical staff for availability.
O’ring Cord - Imperial & Metric Extruded 70 durometer nitrile o’ring cord is available in an extensive range of sizes. Other elastomers, including viton, neoprene, E.P.D.M & silicone, are available in a smaller range of sizes and lower quantities. 70 durometer nitrile X’Ring cord is also available in nominal imperial sizes. Where moulded o’rings are not available in a specific size, we can offer spliced o’rings ed with cyanoacrylate, or vulcanised o’rings. However, ed o’rings are only suitable for static applications.

Silicone Grease & The Importance Of Lubrication Lubrication is extremely important for o’rings working in all static and dynamic applications. It should be kept in mind that the greatest benefit will be obtained, if the lubricant is used at the time of installation. Using a silicone based grease during assembly will help to protect the o’ring from damage through abrasion, pinching, and cutting. As an additional benefit, the surface film formed by such a lubricant helps to protect elastomers from atmospheric degradation, extending the service life of an o’ring. Transeals stocks a high performance, silicone based, translucent grease specifically developed for such applications. Non-toxic, and with a working temperature range from -50°C to 200°C, it is an excellent fitting grease for a wide variety of applications. It is packed for convenience in screw topped 250g tubs, or bulk packed in 1kg and 5kg tins.
Storage Conditions & Age Control Storage life varies for all elastomers. However, in normal warehousing conditions, life of even the relatively age-sensitive elastomers is considerable. As a general rule, exclusion of contamination, light (particularly sunlight), oxygen and ozone (air), will ensure the maximum possible shelf life. This can be easily achieved by storing elastomeric seals in polyethylene bags, inside larger cardboard boxes. O’rings should always be stored in a relaxed condition and hence must only be coiled in odd numbers when size does not permit them to be stored uncoiled. Field experience has demonstrated that storage conditions are much more important in determining the useful life of elastomeric seals than is time. Controlling time of storage can serve to de-emphasise the need for adequate control of storage conditions, and this philosophy may result in the use of deteriorated seals, or in the wasteful destruction of perfectly good seals.

Standard SAE O’rings & Flange Seals In many cases, standard o’rings are not suitable for flange sealing due to marginal conditions. Anything from high temperatures, extreme pressures, or unsuitable surface finish on the flanges, can diminish their operational life. For this reason, Transeals stocks four different types of o’rings and flange seals to suit standard SAE flanges. Choosing the appropriate one will ensure maximum seal life, reducing down time, and therefore overall operating costs.

Standard duty o’ring for general service applications. Standard duty o’ring for high temperature service applications. Heavy duty flange seal constructed from two bonded lamina of polyurethane varying in compound and durometer. The outer lamina provides excellent extrusion resistance for the inner lamina, which exhibits extremely low compression set and has excellent sealing characteristics. This unique combination of bonded lamina provides improved sealing performance and longer service life than can normally be obtained from standard duty o’rings. Heavy duty flange seal moulded from 93 shore A polyurethane, especially compounded for low compression set values. Designed for extreme service applications, the OV series flange seals have good abrasion resistance, making them the ideal choice for situations where the surface finish of the flange is marginal.

The Origin Of The O’ring The origins of the o’ring can be traced back to mid 19th century, when cast iron was chosen as a seal for steam engine cylinders. Results showed that an elastomeric material was required to aid sealing. As time ed, and engineers learned how to use rubber, the o’ring was truly invented. Today it has become the worlds most popular seal. Its simple shape, low space requirements, and easy fitting, combine with the large range of materials from which it can be made, to suit a wide variety of sealing applications. As the worlds most simple sealing device, we also find the o’ring to be the most abused. Simple, straight forward information about sizes and housing details, covering both the metric and imperial ranges, can be extremely difficult to find. Therefore, we have attempted to put it all together in a concise, easy to follow format.
Helpful Tips About O’rings •
When stating o’ring size, it is an international convention to specify the o’ring by its inside diameter (ID) x cross-section (CS).
•
All metric o’ring cross-sections are actual sizes.
•
All imperial o’ring cross-sections are nominal sizes. Example : a 1/8 nominal o’ring has an actual cross-section of 0.139”, not 0.125”.
•
The overall performance of an o’ring is directly related to the extrusion gap, groove dimensions, and surface finishes of the housing, as well as the appropriate selection of elastomer and compound.
•
Due to the vast range of metric o’ring sizes throughout the world, not all are readily available within Australia. Please confirm availability of your selected size in an appropriate elastomer and compound at the design stage.
•
Imperial o’rings are available in a wider range of elastomers and durometers ( hardness ) than are metric o’rings. This should be kept in mind at the design stage.
•
The two primary considerations when selecting an elastomer, are that it should be both compatible with the system fluid being used, and capable of operating within the required temperature range.

The Importance Of Cross-Section One of the greatest problems people experience when identifying o’rings, is getting an accurate measurement of the cross-section (CS). This task can be made a lot easier by ascertaining the origin of the machine to which it belongs. As each country works to a specific set of standard cross-sections, this information can be used to eliminate many potential selections. The following table shows common o’ring crosssections, and indicates those countries which use them.

General Service Applications
-40°C to 110°C
Nitrile is the most widely used elastomer in the seal industry. It has an excellent balance of desirable properties, with good resistance to mineral based hydraulic fluids, water, alcohol, and many other media. N9 is recommended for high pressure static applications.
V7 75 Durometer V9 90 Durometer
-35°C to 205°C
Viton has a resistance to a broader range of chemicals than any other elastomer. It has excellent mechanical properties, with good resistance to compression set and high temperatures. V9 is recommended for high pressure static applications.
C7 70 Durometer
-55°C to 140°C
Neoprene is unusual, in that it has moderate resistance to both mineral based hydraulic fluids and weather (ozone, sunlight, oxygen). It is also resistant to many refrigerants (freons, ammonia), and mild acids.
E7 70 Durometer
-55°C to 150°C
E.P.D.M. is resistant to water, steam, acids, alkalis, brake fluid, phosphate esters, and ketones, with excellent weathering properties. It has poor resistance to mineral based fluids.
-85°C to
Silicone has a very low physical strength and should be limited to static applications only. It is compatible with a wide range of fluids, as well as hot air.

Back-Up-Washers & The Effect Of Pressure Back-up-washers (BUW’s) are not in themselves a pressure seal. Specifically, they are a device to reduce o’ring extrusion, thereby enabling an o’ring to withstand much higher pressures with a given diametral clearance. The use of BUW’s allows extrusion gaps to be increased, permitting larger diametral clearances between the piston & bore or rod & gland at a given pressure, thus reducing machining costs. The figures below show the effect of increasing pressure on an o’ring, and that of introducing a BUW when pressure becomes too great for an o’ring by itself. The 3rd figure shows an o’ring at the extreme of its operating abilities. With the increase in pressure for figure 4, the o’ring is forced into the extrusion gap and destroyed. This problem can only be solved by reducing the diametral clearance (increasing machining costs), or the introduction of BUW’s as in figure 5.
B.U.W’s - Availability To Suit Standard Imperial O’rings Transeals stocks a comprehensive range of BUW’s to suit standard imperial o’rings (refer pages 8-13 for o’ring sizes) manufactured from 90 durometer nitrile (N9). These can be stretched during installation, enabling them to be fitted without being scarf cut. P.T.F.E BUW’s are also stocked in a wide selection of these sizes and can be manufactured in-house for the entire range. Being made from a harder material than the N9 BUW’s, they are suitable for more extreme applications. However, they do not stretch and must be either fitted into a 2 part housing, or scarf cut prior to fitting. B.U.W’s - Availability To Suit Standard Metric O’rings Unlike imperial o’ring standards, not all metric o’ring standards contain specifications for BUW’s. Therefore, it is not possible to get BUW’s to suit all metric o’rings. Transeals stocks metric BUW’s manufactured from P.T.F.E and HYTREL in a selected range of common sizes to suit G & P series o’rings (refer to page 14 for JIS B 2401:1967 o’ring sizes). Non-standard sizes can be manufactured in-house from P.T.F.E.
Extrusion Curves For 70 Duro O’rings & 90 Duro BUW’s Use these curves to determine maximum diametral clearance G.This value should always be kept to a minimum.

Standard Imperial X’Rings X’Rings are an elastomeric seal designed to replace o’rings in certain applications. They are basically square in cross-section, making spiral twist impossible, with concave sides to reduce the area. The frictional resistance for X’Rings is less than that of the corresponding o’ring for pressures up to 600 psi. X’Ring dimensions correspond with those for standard imperial o’rings, and as such can be fitted to existing o’ring grooves. Transeals stocks an extensive range of 80 durometer nitrile (N8) X’Rings in standard imperial sizes. Other elastomers and compounds are available only in selected sizes and limited quantities. our technical staff for availability.
O’ring Cord - Imperial & Metric Extruded 70 durometer nitrile o’ring cord is available in an extensive range of sizes. Other elastomers, including viton, neoprene, E.P.D.M & silicone, are available in a smaller range of sizes and lower quantities. 70 durometer nitrile X’Ring cord is also available in nominal imperial sizes. Where moulded o’rings are not available in a specific size, we can offer spliced o’rings ed with cyanoacrylate, or vulcanised o’rings. However, ed o’rings are only suitable for static applications.

Silicone Grease & The Importance Of Lubrication Lubrication is extremely important for o’rings working in all static and dynamic applications. It should be kept in mind that the greatest benefit will be obtained, if the lubricant is used at the time of installation. Using a silicone based grease during assembly will help to protect the o’ring from damage through abrasion, pinching, and cutting. As an additional benefit, the surface film formed by such a lubricant helps to protect elastomers from atmospheric degradation, extending the service life of an o’ring. Transeals stocks a high performance, silicone based, translucent grease specifically developed for such applications. Non-toxic, and with a working temperature range from -50°C to 200°C, it is an excellent fitting grease for a wide variety of applications. It is packed for convenience in screw topped 250g tubs, or bulk packed in 1kg and 5kg tins.
Storage Conditions & Age Control Storage life varies for all elastomers. However, in normal warehousing conditions, life of even the relatively age-sensitive elastomers is considerable. As a general rule, exclusion of contamination, light (particularly sunlight), oxygen and ozone (air), will ensure the maximum possible shelf life. This can be easily achieved by storing elastomeric seals in polyethylene bags, inside larger cardboard boxes. O’rings should always be stored in a relaxed condition and hence must only be coiled in odd numbers when size does not permit them to be stored uncoiled. Field experience has demonstrated that storage conditions are much more important in determining the useful life of elastomeric seals than is time. Controlling time of storage can serve to de-emphasise the need for adequate control of storage conditions, and this philosophy may result in the use of deteriorated seals, or in the wasteful destruction of perfectly good seals.

Standard SAE O’rings & Flange Seals In many cases, standard o’rings are not suitable for flange sealing due to marginal conditions. Anything from high temperatures, extreme pressures, or unsuitable surface finish on the flanges, can diminish their operational life. For this reason, Transeals stocks four different types of o’rings and flange seals to suit standard SAE flanges. Choosing the appropriate one will ensure maximum seal life, reducing down time, and therefore overall operating costs.

OV Series Flange Seal
Standard duty o’ring for general service applications. Standard duty o’ring for high temperature service applications. Heavy duty flange seal constructed from two bonded lamina of polyurethane varying in compound and durometer. The outer lamina provides excellent extrusion resistance for the inner lamina, which exhibits extremely low compression set and has excellent sealing characteristics. This unique combination of bonded lamina provides improved sealing performance and longer service life than can normally be obtained from standard duty o’rings. Heavy duty flange seal moulded from 93 shore A polyurethane, especially compounded for low compression set values. Designed for extreme service applications, the OV series flange seals have good abrasion resistance, making them the ideal choice for situations where the surface finish of the flange is marginal.
