Piston Seal PIP Profile

Piston Seal PIP Profile


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.

Note: The PIP profile may be purchased as an assembly (Type B PolyPak and PIP ring) or separately as a PIP ring only. If purchasing as an assembly, the standard material is a 4615 Type B PolyPak with 4617 PIP ring. If you desire alternate material combinations, please order the PIP ring and Type B PolyPak separately. Call your Zatkoff Seals & Packings representative for details.
