U-SEAL (CAT CT30161-02501)

A worn U-seal can allow fluid leakage, reducing system pressure and causing erratic operation. This aftermarket replacement part references CAT as the OE maker and cross-references part number CT30161-02501. The U-seal functions as a static or dynamic seal, preventing fluid bypass between mating surfaces. A common failure consequence is gradual loss of lubrication, leading to accelerated component wear. During routine service, a cracked or hardened U-seal may indicate exposure to heat or incompatible fluids. Verify the serial number or application, then call (562) 693-7748. This part is a seal type designed to contain fluid under pressure in a closed system.
