RING - WIPER (Komatsu KO34B-63-17830)

A worn wiper ring can allow contaminants to enter a sealed assembly, accelerating component wear. This aftermarket replacement part references the Komatsu catalog number KO34B-63-17830. The wiper ring functions as a mechanical seal element that scrapes debris from a moving shaft or rod. When the ring fails, external dirt and moisture can bypass the seal, leading to premature failure of internal bearings or seals. In a typical application, the ring is installed in a groove and maintains constant contact with the sliding surface. The item ships at approximately 0.044 pounds. Verify the serial number or application, then call (562) 693-7748.
