The PPY piston rod seal is a high-performance hydraulic sealing part developed for reciprocating piston rods of hydraulic cylinders. It is designed to stop hydraulic oil leakage along the rod surface and block external dust, sand and debris from getting into the cylinder chamber.
Made of premium polyurethane material, the PPY rod seal features superior tear resistance, low friction and reliable anti-extrusion performance. Its optimized sealing lip delivers uniform contact pressure on the piston rod. It maintains stable sealing performance under fluctuating hydraulic pressure and continuous reciprocating cycles, reducing friction heat and slowing down wear during long-time dynamic operation.
This PPY piston rod seal works across a wide temperature and pressure range, and is compatible with most common hydraulic oils. It can operate steadily under heavy loads and harsh working environments, effectively resisting abrasion and extrusion damage.
It is widely applied in construction machinery, forklifts, hydraulic presses, mining equipment and general industrial hydraulic cylinders. Easy to install and replace, the PPY rod seal helps reduce oil leakage failures and cut equipment maintenance and replacement costs.
