U-Seal, 1-1/2"X1-7/8"X3/8"

U-Seal, 1-1/2"X1-7/8"X3/8"

The DRTU18-1.50-37 U-Seal is a dynamic rod seal engineered for maximum life and reliability in hydraulic cylinder applications. Its added secondary lip on the inside diameter helps deliver reduced leakage, lower friction, increased stability, and keeps air and contaminants from sneaking into the cylinder—because the only thing that should be moving freely is the rod, not your hydraulic fluid.
