Rod seals are used in hydraulic cylinders for fluid sealing. They are external to the cylinder head and seal against the cylinder’s rod, preventing leakage of fluid from within the cylinder to the outside.

A hydraulic rod seal is usually manufactured in  PTFE based material or  polyurethane . Specially engineered for fluid power applications, these compounds provide exceptional resistance to wear and outstanding extrusion properties. Options are available that are compatible with virtually all media, they demonstrate unrivalled temperature performance.
