The PNY piston rod seal is a high-performance hydraulic sealing element engineered for reciprocating piston rods in hydraulic cylinders. Its primary function is to prevent outward leakage of hydraulic fluid along the rod and keep dust, grit and other external contaminants out of the cylinder’s inner cavity.
Manufactured from high-grade polyurethane material, the PNY rod seal has excellent tear resistance, low friction coefficient and strong anti-extrusion ability. Its precision-designed sealing lip creates uniform contact pressure on the piston rod surface. It maintains stable sealing performance under variable working pressure and repeated reciprocating cycles, minimizing friction heat and slowing down abrasion during continuous dynamic operation.
This PNY piston rod seal supports a wide range of working temperature and pressure, and is compatible with most standard hydraulic oils. It can run reliably under heavy cyclic loads and tough working conditions, effectively resisting abrasion and extrusion damage.
