Product Description
The UOP Piston Seal is a single acting, U-cup piston seal with an asymmetrical design. The seal can be in a double-acting cylinder by using two seals in a back-to-back arrangement. The outer diameter of the seal has a shortened lip which increases the cross-sectional area. This seal is both an excellent dynamic as well as static seal. It can withstand pressures of up to 40Mpa considering a smaller extrusion gap. The UOP Piston Seal is mostly used in construction and earth-moving machinery.
