PISTON SEALS

Piston seals are typically double acting/bi-directional but can also be provided in a single acting/uni-directional configuration if the application demands. Piston seals are normally installed onto a piston of either solid or split design and provide a static seal across the internal diameter and both static and dynamic sealing against the cylinder wall or bore of a hydraulic or pneumatic cylinder. The main purpose of a piston seal is to prevent fluid media to escape across the piston head into the opposing chamber. By sealing against the cylinder wall a pressure build up is produced on one side of the piston head which in turn makes the cylinder extend or retract according to wishes of the machine user. The correct choice of piston seal is an important factor when designing or repairing a hydraulic or pneumatic cylinder.

DMR offers a wide range of high performance piston seals and can engineer a solution for the most arduous of applications. We can provide you with engineered sealing solutions for applications involving high pressure, low pressure, high speed, high temperature and extreme low temperature. When DMR piston seals are combined with the correct range of wiper seals, guide rings and rod seals you can be assured of a leak free, long life performance.
