PDF type rod seal is a professional single-acting sealing part specially designed for hydraulic cylinder piston rods. It is mainly used to block hydraulic oil leakage along the reciprocating piston rod and prevent external dirt and dust from invading the hydraulic system, ensuring stable operation of cylinders under continuous working conditions.
Made of high-performance polyurethane raw material, the PDF rod seal features excellent wear resistance, good tear resistance and low compression set. It can maintain stable elasticity under long-term hydraulic pressure, not prone to permanent deformation. The refined sealing lip structure effectively reduces contact friction between the seal and piston rod surface, cutting friction heat and minimizing rod abrasion, which greatly prolongs the service life of the whole hydraulic assembly.
The PDF rod seal conforms to standard installation groove dimensions for simple assembly. It works steadily under medium pressure, compatible with most conventional hydraulic fluids and adapts to a wide operating temperature range. It is widely applied in construction machinery, forklifts, hydraulic presses and general industrial hydraulic cylinders.
Every PDF piston rod seal is subject to strict quality testing before shipment. We provide plenty of standard sizes and support custom dimension production to meet different industrial sealing requirements. If you are looking for reliable hydraulic rod seals with consistent sealing performance, PDF type rod seal is your ideal sealing option.
