PLATE - SEAL (CAT CT21011-31702)

A worn seal plate 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 CT21011-31702. The plate functions as a sealing component, providing a stationary surface against which a moving seal element compresses. Its plain mechanical role is to maintain a consistent gap between mating surfaces under clamping force. A common failure consequence is gradual loss of containment, leading to contamination ingress and accelerated wear of adjacent parts. The item ships at approximately 0.028 pounds. Verify the serial number or application, then call (562) 693-7748.
