O-RING (CAT CT27V89C17)

A damaged retaining ring can lead to component separation or leakage in sealed assemblies. During inspection, a retaining ring may show signs of wear, distortion, or corrosion that compromise its holding force. Keeping a retaining ring in sound condition helps maintain proper alignment and pressure within the assembly. This aftermarket replacement part references CAT as the OE maker and cross-references part number CT27V89C17. The O-ring type provides a seal between mating surfaces to prevent fluid or gas escape. A common failure consequence is loss of seal integrity, resulting in system pressure drop or contamination ingress. Verify the serial number or application, then call (562) 693-7748.
