Base Parts and Engine Assembly

In the base parts of an engine, the O Ring Seal is utilized to secure connections and interfaces, ensuring that fluids and gases remain contained within their designated pathways. This is particularly important in the engine assembly where precise sealing is required to maintain compression and prevent contamination.

Camshaft and Related Components

For the camshaft and camshaft and gear, the O Ring Seal plays a significant role in sealing oil passages. This ensures that lubrication is consistently delivered to critical moving parts, reducing friction and wear. Proper sealing also helps in maintaining the integrity of the oil film, which is essential for the smooth operation of the camshaft.

Connecting Rod and Piston

In the connecting rod and piston assembly, the O Ring Seal is employed to seal oil feed passages. This is vital for piston cooling, where the seal ensures that oil reaches the piston cooling nozzle and piston cooling hole plug without leakage. Effective sealing here contributes to the dissipation of heat, prolonging the lifespan of the piston and connecting rod.

Lubrication Systems

The O Ring Seal is a key component in the lubricating oil pump kit and lubricating oil supply tube. It ensures that oil is delivered under pressure to various engine parts without any loss, maintaining consistent lubrication across the engine.
