SEAL - O-RING (Clark CL3719387)

A damaged O-ring seal can allow fluid leakage, leading to pressure loss in a sealed system. The Clark catalog reference for this part is CL3719387. This aftermarket replacement seal is a circular elastomeric component that compresses between mating surfaces to prevent fluid or gas passage. Over time, exposure to heat or chemicals can cause the rubber to harden and crack, resulting in a gradual leak. A leaking O-ring may cause intermittent system performance issues before complete failure occurs. Verify the serial number or application, then call (562) 693-7748. This item ships at approximately 0.004 pounds.
