Parker's Type B PolyPak® (BPP Profile) is a squeeze seal with a symmetrical profile for use in either rod or piston 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 Type B PolyPak is excellent for cutting fluid film. The sharp beveled lip is formed by a precision knife trimming process during manufacture. A wide selection of sizes and alternate compounds allow this profile to match up with many hydraulic applications. The Type B PolyPak is and economical choice as a stand alone rod seal or can be used in tandem with a buffer seal. In piston applications, this seal will function as a unidirectional seal. Type B PolyPaks should not be installed back to back, in bi-directional pressure applications, as a pressure trap between the seals may occur.
