PNY type rod seal is a high-performance single-acting sealing component developed for hydraulic cylinder piston rods. Its main function is to prevent hydraulic medium leakage along the reciprocating piston rod and stop dust, grit and other impurities from entering the cylinder interior, protecting the hydraulic system steadily.
Produced from premium polyurethane material, the PNY rod seal boasts remarkable wear resistance, great tensile strength and low compression set. It retains stable elasticity under continuous hydraulic pressure load, resisting aging and deformation during long reciprocating movement. The optimized lip design reduces friction between the seal and rod surface, lowering friction heat generation and extending the service life of both the seal and matching piston rod.
This PNY rod seal matches standard hydraulic groove sizes for quick and convenient installation. It performs reliably under medium working pressure and is compatible with most common hydraulic oils over a wide operating temperature range. Typical applications include engineering machinery, material handling equipment, hydraulic presses and general industrial hydraulic cylinders.
All PNY piston rod seals pass rigorous quality checks prior to delivery. We supply abundant standard sizes and support custom size processing to satisfy various engineering needs. If you seek dependable hydraulic rod seals with stable sealing performance, the PNY type rod seal will be your practical sealing solution.
