The urethane U-cup design provides an excellent heavy-duty seal for either piston or rod applications. Urethane U-cups work well in both static and dynamic applications.
Symmetrical, rod and piston styles are available in a range of sizes. The non-symmetric styles provide the added benefits of: reduced seal movement, added stability in static applications and protection of the dynamic lip during installation. The rod style provides improved sealability on the I.D., well the piston style provides improved sealability on the O.D.
Double lip versions of the Rod (RO DL) and Piston (PI DL) oriented urethane U-cup are available.
