O-RING (JCB JC57K6)

JC57K6: A damaged retaining ring can allow assembled components to separate unexpectedly during operation. The JCB catalog reference for this aftermarket replacement part is JC57K6. This O-ring type retaining ring provides a sealing and retention function between mating surfaces. A common failure consequence is gradual fluid leakage past the ring, leading to pressure loss. Keeping the ring in sound condition helps maintain consistent sealing force in the joint. The ring is a simple elastomeric component that compresses to fill the gap between parts. Verify the serial number or application, then call (562) 693-7748.
