2" x 1.625 x .281 Parker® 2 Pc 4300 PU/NBR High Temp Piston Seal

The PSP-A profile is a squeeze type, new style bi-directional piston seal for use in light to medium duty hydraulic applications. Available from proprietary Parker polyurethanes, the PSP offers low friction, abrasion and extrusion resistance. The nitrile elastomer energizer ensures resistance to compression set to increase seal life. The PSP-A profile's geometry provides a fluid reservoir between the two sealing lips which holds system fluid, resulting in reduced breakaway and running friction. Designed to retrofit grooves for a single O-ring or an O-ring with two back-ups, the PSP-A profile is easy to install and resists rolling and twisting in long stroke applications. Request Quote
