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