It provides a secure seal between mating components, helping prevent oil leakage and maintain the integrity of the engine lubrication system.

What Does It Do?

The seal prevents engine oil escaping from the connection between the oil tank and oil filter assembly, maintaining an oil-tight joint.

Why Does It Fail?

Common causes include:

• Rubber deterioration with age
• Hardening from heat exposure
• Compression and loss of elasticity
• Damage during servicing
• Incorrect installation

When Should It Be Replaced?

Replace the seal if oil leakage is visible around the connection, the seal has hardened or become damaged, or the associated components are dismantled for servicing.

Installation Notes

Clean the mating surfaces and inspect them for damage before fitting. Ensure the seal is correctly seated and check for leaks after reassembly.
