CUP 1,94X0,63 (CAT CT21206)

A damaged cup can allow fluid leakage, reducing system pressure and causing erratic operation. The aftermarket replacement part references CAT as the OE maker and cross-references part number CT21206. This cup type serves as a sealing component, creating a barrier between two joined surfaces. Its plain mechanical function is to compress under fastener torque to fill gaps. A concrete generic failure consequence is that a worn cup may lead to gradual seepage, which can attract debris and accelerate wear. The catalog lists the spec as 94X0. Verify the serial number or application, then call (562) 693-7748. The item ships at approximately 0.26 POUNDS.
