PERFORMANCE ADVANTAGES
Parker’s PSP Profile is a squeeze type, polyurethane cap style piston seal for use in light to medium duty, bi-directional hydraulic applications. Available from proprietary Parker polyurethanes, the PSP offers low friction, abrasion and extrusion resistance. The lathe-cut nitrile elastomer energizer ensures resistance to compression set to increase seal life. The PSP profile’s geometry provides a fluid reservoir between the two sealing lips which holds system fluid, resulting in reduced breakaway and running friction.

The PSP Profile’s geometry provides a fluid reservoir between the two sealing lips which holds system fluid, resulting in reduced breakaway and running friction. Additional features of the PSP Profile include:
• Designed to retrofit grooves for a single o-ring or an o-ring with two back-ups (wide)
• Easy to install
• Resists rolling and twisting in long stroke applications.

Available in polyurethanes, including Parker’s proprietary Resilon®, the PSP Profile provides
• Long life
• Extrusion resistance
• Low compression set

Standard Materials:
• P4622A90 Ultrathane® polyurethane; Temp -65 / +225F; Pressure* 5000 psi; Surface speed
