- In addition to protecting the wheel bearings from contamination, wheel oil seals also help to prevent oil leakage from the wheel hub. This is particularly important in heavy-duty vehicles such as trucks and buses, where the wheels are subjected to high loads and harsh operating conditions. A leaking wheel oil seal can result in oil loss, which can lead to inadequate lubrication of the wheel bearings and potentially cause serious damage to the wheel assembly.
Failure Modes of Oil Seals

Lubricant Amount - Seals will always perform best when lubricated, however in some machines there are more likely to be dry spells. For these cases, selecting a leather or PTFE seal will be beneficial, as both can operate with less lubrication than others.

The car head gasket, also known as the cylinder head gasket, is a critical sealing component in the engine that plays a pivotal role in maintaining the integrity of the combustion chamber. This gasket is designed to seal the cylinder head to the engine block, preventing the leakage of coolant, oil, and combustion gases. A properly functioning car head gasket is essential for ensuring optimal engine performance, preventing overheating, and maintaining the overall efficiency of the engine.
