DESCRIPTION

The PRC ring is a “Pressure Inverting Pedestal” when combined with a Type B PolyPak it provides excellent, bi-directional piston sealing in hydraulic applications. The PRC 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 PRC 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.
