550-5496: 278.99mm O-Ring Seal

Description:
An O-Ring Seal is a type of mechanical seal that is used to prevent leakage of fluids between two mating surfaces. It is a circular-shaped ring typically made of an elastomeric material, such as rubber, silicone, Viton, and Teflon. 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:
• Can withstand high-pressure conditions and temperatures.
• Maintain their original shape even when compressed over time.

Applications:
An O-Ring Seal acts as a barrier that inhibits fluid from leaking out of the swing drive unit, mostly used in Cat 320D2 L, 320D2, 320D3 GC, 320D3, and 323D3 Excavators.
