1.687 x 2.312 x .5" Parker® Molythane Type B Loaded Lip Seal PolyPak®

Type B PolyPak® is a squeeze seal with a symmetrical profile for rod applications. The rectangular shape of its cross section ensures stability in the gland. 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. 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® Request Quote
