PTFE & Polyurethane materials

Our hydraulic rod and piston seals are usually manufactured using PTFE or a polyurethane-based material with specific fillers. Specially engineered for fluid power applications, these compounds provide exceptional resistance to wear and outstanding extrusion properties. Versions that are compatible with virtually all media demonstrate unrivalled temperature performance.
