A Pneumatic Rod Seal is a critical sealing component used in pneumatic systems, specifically designed to prevent air or gas leakage and protect the internal components of cylinders, including the piston, rod, and other sealing elements. The main purpose of the pneumatic rod seal is to maintain the efficiency of the system by ensuring a tight seal around the rod as it moves in and out of the cylinder, while also preventing contaminants from entering the cylinder.

UHS and UNR Rod Seals are high-quality polyurethane hydraulic rod seals designed for reliable sealing performance in hydraulic cylinders. These seals are used to prevent oil leakage from the rod side while ensuring smooth, low-friction reciprocating motion.

The UHS Rod Seal features a single-lip design, suitable for standard to high-pressure applications, offering excellent wear resistance and long service life.
The UNR Rod Seal comes with a double-lip profile, providing enhanced sealing efficiency and superior performance in heavy-duty and high-pressure environments.

Manufactured from premium-grade PU material, UHS & UNR seals deliver excellent resistance to abrasion, extrusion, and pressure fluctuations, making them ideal for both industrial and mobile hydraulic systems.
