U-Seal, 1-1/2"X1-7/8"X5/16"

U-Seal, 1-1/2"X1-7/8"X5/16"

The DRTU18-1.50-31 U-Seal (1-1/2" x 1-7/8" x 5/16") is a high-performance dynamic rod seal engineered for maximum life and reliability in hydraulic cylinder applications. Designed with a secondary inner lip, this seal reduces leakage, lowers friction, increases stability, and helps prevent air and contaminants from entering the system. Built for demanding pressure environments where performance matters.
