PARKER® BEVELED LIP MOLYTHANE LOADED LIP SEAL POLYPAKS®
Type B PolyPak® is a squeeze seal with a symmetrical profile for use rod applications. The rectangular shape of its cross section ensures stability in the gland. The standard Molythane® shell provides high wear resistance and the O-ring energizer functions as a spring to maintain sealing contact under low pressure or vacuum applications. The beveled lip design of the seal is excellent for cutting fluid film and is formed by a precision knife trimming process. A wide selection of sizes and alternate compounds allow this profile to match up with many hydraulic applications. The Type B PolyPak® is an economical choice as a stand-alone seal or can be used in tandem with a buffer seal. Dual Type B PolyPak® seals should not be installed back-to-back in bi-directional pressure applications, as a pressure trap between the seals may occur. Instead, for bi-directional piston sealing, incorporate a PIP Ring®
