This profile combines a “Pressure Inverting Pedestal” to a single acting energized U seal to provide excellent, bi-directional piston sealing in hydraulic applications.
The PIP Ring conforms to the beveled sealing lips of a energized u seal to provide extrusion resistance when pressure is applied to the heel side of the seal.
The PIP Ring profile requires only a single seal groove for installation. This eliminates the use of two U seals on the piston to save space and increase bearing length.
