4 x 3.625 x 0.281 2 Pc Polyurethane/NBR Piston Seal Assembly Inch

PSP seals are bi-directional squeeze type piston seals used as direct substitutes for o-rings, T-seals and Cap seals in industrial no-back-up o-ring grooves. The unique geometry of the PSP seal design creates a fluid reservoir between the two level bi-lip sealing surfaces. This feature provides extra lubrication resulting in reduced breakaway and running friction. PSP seals are manufactured from a proprietary low friction urethane, which has excellent abrasion, tear and extrusion resistance. PSP seals provide positive, no-drift sealing at a continuous service temperature range from -65° to 220° F, and pressures up to 5000 PSI with the recommended groove dimensions and tolerances. Both styles fit the same groove.
