Hydraulic rod seals prevent hydraulic fluid from leaking out along the piston rod as it extends and retracts, while keeping contaminants out of the cylinder. We supply rod seals in single-acting and double-acting profiles, manufactured from high-modulus polyurethane, PTFE, and NBR to handle pressures up to 400+ bar and rod speeds found in mobile and industrial hydraulics.
Our rod seals are available in standard DIN/ISO profiles (compact seals, U-cups, step seals) as well as custom cross-sections machined to match OEM cylinder drawings. Typical applications include excavators, hydraulic presses, injection molding machines, and marine deck equipment. Ask our team for a cross-reference if you have an existing part number or sample.

Hydraulic Rod Seals
Applications
Hydraulic Rod Seals are critical sealing components designed to prevent hydraulic fluid from leaking along the piston rod while protecting the hydraulic cylinder from external contaminants such as dust, dirt, moisture, and debris. Installed in the cylinder gland, rod seals ensure efficient pressure retention, smooth rod movement, and long-lasting cylinder performance in demanding hydraulic applications. PM Hydraulic Rod Seals are manufactured using premium-grade polyurethane, PTFE, and NBR materials to provide superior sealing performance, low friction, and exceptional wear resistance even under high-pressure operating conditions.
