Description:
An O-Ring Seal is a type of mechanical seal used in engines to prevent oil from leaking out of the crankshaft. It is a circular ring made of a flexible and durable material, such as rubber or silicone, that is placed between the crankshaft and the engine block. O-Ring Seals are designed to fit into a groove or recess in one of the mating surfaces and compress against the other surface when the two parts are assembled.

Attributes:
• Maintain their original shape even when compressed over time.
• Can withstand the vibrations and movement of the engine.

Applications:
An O-Ring Seal is used to create a tight seal between the crankshaft and the engine block, mostly used in Cat 320D3 GC and 320D3 Excavators.
