Parker’s Standard PolyPak® (SPP) is a square cross-section squeeze seal with a symmetrical profile for use in either rod or piston applications.  The standard Molythane shell provides high wear resistance and the O-ring energizer functions as a spring to maintain sealing contact under low pressure.  The standard PolyPak utilizes a scraper lip design formed by a precision trimming process.  The scraper edge wipes both fluid film and contamination away from the seal.  A wide selection of sizes and alternate compounds allow this profile to match up with many hydraulic applications.
