O-RING, 2.5MM X 21MM I.D. (CAT CT0350-00210)

CT0350-00210: A worn retaining ring can allow a shaft or bore to lose its axial retention, leading to component separation. This aftermarket replacement part references CAT as the OE maker and cross-references part number CT0350-00210. The part is an O-ring with a 2.5MM cross-section and a 21MM inside diameter. Its general function is to create a static seal between two mating surfaces, preventing fluid or gas leakage. A common failure consequence is that a degraded O-ring will permit gradual seepage, reducing system pressure over time. The item ships at approximately 0.004 POUNDS. Verify the serial number or application, then call (562) 693-7748.
