Description
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.
