U-Seal, 1-1/8"X1-3/8"X3/16"

U-Seal, 1-1/8"X1-3/8"X3/16"

The U12-1.12-18D Style 800 U-Seal is a tough polyurethane U-seal designed for dependable hydraulic sealing, even when the system is sitting idle. Its four-lobed expander ring energizes the sealing lips at zero pressure to help prevent “weeping”—because nobody wants to come back to a machine that’s marking its territory.
