26 x 27.5 x .75" Parker® Molythane Standard Loaded Lip Seal PolyPak®

Parker® Standard PolyPak® is a squeeze seal with a symmetrical profile for use in either rod or piston applications. The standard Molythane® shell provides high wear resistance. The O-ring energizer functions as a spring to maintain sealing contact under low pressure. This utilizes a straight cut scraper lip design. The scraper edge wipes both fluid film and contamination away from the seal. An economical choice as a stand alone rod or piston seal. With less squeeze force than the Deep or Type B profiles, can be installed back-to back, in separate glands, for bi-directional sealing. To protect against pressure trapping, it is recommended that the O-ring be removed from the side facing the lower pressure side of the application. Request Quote
