Hydraulic piston seals seal the moving piston against the cylinder bore, preventing internal leakage (bypass) between pressure chambers and maintaining cylinder efficiency. We stock and manufacture piston seals in glyd rings, compact seals, and step-type profiles, using polyurethane, PTFE with bronze fill, and NBR compounds selected for your pressure rating and duty cycle.
Our piston seals are used across heavy equipment, hydraulic presses, steel and aluminum mills, and offshore hydraulic systems where consistent performance under shock loading and high cycling is critical. Custom compounding and machining are available for non-standard bore sizes.

Hydraulic Piston Seals are designed to create a reliable sealing barrier between the piston and cylinder bore, preventing internal fluid leakage (bypass) between pressure chambers. They play a vital role in maintaining hydraulic pressure, improving cylinder efficiency, and ensuring smooth, reliable operation. PM Hydraulic Piston Seals are manufactured from high-performance polyurethane, PTFE, and NBR compounds, providing excellent wear resistance, low friction, and outstanding sealing performance in high-pressure hydraulic systems. They are available in standard and custom profiles to suit a wide range of industrial applications.
