3,Shift lever seal: EPDM O-rings can be applied to the sealing components of the transmission shift lever to prevent fluid leakage and the entry of external contaminants.

 

4,Oil pump seal: EPDM O-ring can be used to seal the transmission oil pump to ensure normal circulation and lubrication of the transmission oil.

 

5,Temperature sensor seal: EPDM O-ring can be used to seal the transmission temperature sensor to prevent liquid leakage and external contaminants from entering.

 

These are some common application parts of EPDM Rubber AS568 O-rings in automotive Gearboxes. They are used for sealing and protection, ensuring the normal operation of the transmission and the reliability of the lubrication system. The specific application depends on the transmission design and configuration.

Common Causes of O-Ring Failure and Prevention Methods

O-ring failure is often caused by a combination of factors including improper installation, allowing for too much or too little compression in the gland design, inadequate lubrication, abrasion, or using an O-ring seal that is the incorrect size or type of elastomer for your application. Here are a few common sources of rubber oring failure and what you can do to prevent issues.

 

 Abrasion.
Abrasion is a common cause of o ring failure and can result from an improper finish of the surface in dynamic contact with the O-ring. If the surface around the O-ring is too abrasive, or even too smooth, the surface will be unable to hold lubricant. Issues with O-ring abrasion can also occur when a system fluid is not providing proper lubrication, the system fluid contains abrasive particles, or the operating environment involves excessive temperatures.

 

Solutions to this problem include adding proper surface finish and adequately lubricating the O-ring to reduce friction and the risk of wear over time. Another way to prevent abrasion caused by excessive temperatures is to choose an elastomer that is designed to tolerate the operating temperatures where the O-ring is going to be installed. Make sure to review our temperature compatibility chart before selecting an elastomer for your custom AS568 O-ring.

 

Also, check your system fluid regularly for contamination and to ensure that it provides enough lubrication for the O-ring and type of elastomer. If you continue to experience issues, try using a rubber o ring made from an elastomer that provides more abrasion resistance or that is internally lubricated.

 

 Excessive Swelling.
Swelling of the O-ring is caused by the absorption of surrounding fluids. The o ring will continue to swell past the appropriate point if the seal materials are not compatible with the system environment including temperature and fluid type. O-ring swell can eventually lead to issues such as landfills, extrusion, and loss of sealing.

 

To prevent this failure, be sure to choose the proper AS568 rubber O-ring material for your application. You will need an elastomer that can interact with its surrounding environment and any fluids it may come into contact with. If you are unsure of what material to choose, the experts at ACE Seal can help.

 

 Compression Set.
Compression set is the most common cause of O-ring failure. It is caused when the integrity of the seal line is affected by an improper amount of seal squeeze. Typically, an O-ring will return to its original shape when the cross-section is compressed but when a rubber Oring is stretched, it reduces the cross-section and turns the O-ring into a flat oval, which significantly decreases its sealing ability.

 

This happens because of several conditions, including the O-ring being made with inherently poor compression set properties. It can also be caused by improper gland design, excessive temperature, swelling, or over-tightening. Using fluids that are incompatible with your elastomer can also cause compression and O-ring failure.

 

By inspecting your O-rings for effective properties before use, you can prevent this condition. You can also reduce the operating temperature and check for any built-up heat at the seal interface. Use low-set material when possible and make sure the elastomer is compatible with your application temperature and fluids.
