Cylinder Rod Seal, 2"X2-1/2"X3/8"

Cylinder Rod Seal, 2"X2-1/2"X3/8"

The U25-2.00-37B Cylinder Rod Seal is a Style 800 polyurethane U-seal engineered for high-performance hydraulic applications. Molded from tough 95A abrasion-resistant urethane, this seal features a four-lobed expander ring that energizes the sealing lips—even at zero pressure—to help prevent “weeping” when the system is idle. Built to handle demanding pressures and temperature swings, it keeps hydraulic systems sealed tight and operating efficiently.
