PPY type rod seal is a reliable single-acting sealing element designed for hydraulic cylinder piston rods. It is engineered to block fluid leakage from the cylinder while resisting external contaminants, maintaining stable sealing performance during reciprocating rod movement.
Manufactured from high-quality polyurethane compound, the PPY rod seal features outstanding wear resistance, tear strength and compression set resistance. It keeps good elasticity under continuous hydraulic pressure, not easy to harden or deform in long-time operation. The low-friction profile minimizes friction heat, helping to reduce rod wear and extend the service life of hydraulic equipment.
This PPY rod seal fits standard rod seal grooves for simple installation. It works well in medium pressure hydraulic systems and adapts to various hydraulic oils within a common temperature range. Widely used in construction machinery, agricultural equipment, injection molding machines and general industrial hydraulic cylinders.
Every PPY piston rod seal is strictly inspected before shipment. We offer multiple standard sizes and accept custom dimension orders to match different cylinder requirements. If you are looking for durable hydraulic rod seals with stable sealing effect, PPY type rod seal is your cost-effective sealing solution.
