SEAL - WIPER (CAT CT0033070)

A damaged wiper seal can allow contaminants into a sealed assembly, leading to accelerated wear of internal components. This aftermarket replacement part references CAT as the OE maker and carries the cross-reference number CT0033070. The wiper seal functions as a barrier that cleans a reciprocating shaft or rod during each stroke. When the seal fails, external debris can bypass the wiping edge and score precision surfaces. Keeping a wiper seal in sound condition helps maintain consistent sealing pressure and reduces fluid leakage. The part is a generic type-level component, not a specialized assembly. Verify the serial number or application, then call (562) 693-7748.
