Single-acting pneumatic piston seal made with oil-resistant polyurethane specially formulated to give the optimum elasticity, flexibility, and outstanding compression resistance. The special pneumatic sealing edge gives very good tightness with low friction and maintains an effective lubricating film. The piston seal has minimal axial space requirements, an integrated pressure relief to prevent an intermediate pressure build-up, ultra-long life, Ultra-low friction, water resistance, and wide temperature capability.
