U-SEAL (Toyota TY00591-22282-81)

A worn U-seal can allow fluid leakage, leading to reduced system pressure and eventual component failure. This aftermarket replacement part references Toyota catalog number TY00591-22282-81. The U-seal functions as a static or dynamic seal, typically installed in a groove to prevent fluid bypass between mating surfaces. Over time, the sealing lip may harden or crack, causing gradual loss of containment. In a typical application, the seal must maintain a tight barrier under varying temperature and pressure conditions. The item ships at approximately 0.022 pounds. Verify the serial number or application, then call (562) 693-7748.
