O-RING (JLG JL102158)

A damaged O-ring can allow fluid or gas to leak past the seal, reducing system pressure and causing component inefficiency. During inspection, an O-ring may appear cracked, flattened, or brittle, indicating it has lost its sealing ability. O-ring condition directly affects the containment of media within a closed joint or connection. Keeping an O-ring in sound condition helps prevent contamination from entering the sealed area. This aftermarket replacement part references the JLG catalog number JL102158. The O-ring functions as a circular elastomeric seal that compresses between two mating surfaces to block leakage. Verify the serial number or application, then call (562) 693-7748.
