The PDF piston rod seal is a professional hydraulic sealing component designed for reciprocating piston rods of hydraulic cylinders. It is responsible for stopping hydraulic oil leaking out along the rod surface and preventing dust, particles and external pollutants from entering the cylinder interior.
Made of high-performance polyurethane raw material, the PDF rod seal provides outstanding tear strength, low friction coefficient and excellent anti-extrusion property. Its precisely optimized sealing lip ensures uniform contact pressure against the piston rod. It can maintain stable sealing effect under fluctuating hydraulic pressure and continuous reciprocating cycles, reducing friction heat and delaying seal wear during long-time dynamic operation.
This PDF piston rod seal covers a broad working temperature and pressure range and shows good compatibility with most conventional hydraulic fluids. It performs steadily under heavy loads and harsh operating conditions to resist abrasion and extrusion damage.
It is widely applied in construction machinery, forklifts, hydraulic presses, mining equipment and general industrial hydraulic cylinders. Simple installation helps save assembly time. With extended service life, it effectively reduces oil leakage faults and cuts equipment maintenance and replacement expenses.
