The PRY piston rod seal is a high-performance hydraulic sealing element tailored for reciprocating piston rods of hydraulic cylinders. Its main purpose is to block hydraulic oil leakage outward along the rod surface and prevent external dust, grit and impurities from entering the cylinder inner chamber.
Made of premium polyurethane compound, the PRY rod seal delivers excellent tear resistance, low friction coefficient and strong anti-extrusion capability. Its precision-shaped sealing lip creates uniform contact pressure on the piston rod. It maintains consistent sealing performance under fluctuating working pressure and repeated reciprocating cycles, reducing friction heat and slowing down abrasion during long-term dynamic operation.
This PRY piston rod seal supports a wide working temperature and pressure range and is compatible with most standard hydraulic fluids. It runs reliably under heavy cyclic loads and harsh working environments, effectively resisting abrasion and extrusion damage.
