Common causes of oil seal failure
When selecting a 40mm rubber gasket for a specific application, it is important to consider factors such as the operating temperature, pressure, and chemical compatibility to ensure optimal performance and longevity. Additionally, the gasket should be installed properly following manufacturer recommendations to ensure a leak-proof seal.

Some Tools Required During Installation
Loosen all the sump nuts or bolts with a socket, long extension bar and ratchet handle.

Many oil seals are capable of resisting contact with grease, fuel, water, and other elements. Knowing what type of fluid the seal will interact with will help you choose the right oil seal that can withstand those types of fluids.


2. Temperature: Just like pressure, it is very important to choose the right seal that can withstand extreme heat or cold temperatures, depending on the operating environment of your application.
Even though it’s better than other materials in terms of toughness and wear time, it is preferably used in dry-running applications. The salient demerit of this material is its cost.
