SEAL - WIPER (CAT CT30191-02504)

CT30191-02504: A damaged wiper seal can allow contaminants into a sealed assembly, accelerating wear on internal components. This aftermarket replacement part references CAT as the OE maker and cross-references part number CT30191-02504. The wiper seal functions to scrape debris from a moving rod or shaft as it retracts, preventing dirt from entering the housing. If the seal fails, external grit can bypass the primary seal, leading to fluid leaks and reduced component life. During routine service, a wiper seal may appear intact but can lose its lip tension over time. Verify the serial number or application, then call (562) 693-7748.
