Piston Seals

Dynamic and Static Sealing of the Piston Against the Cylinder Barrel

To build up pressure in the piston chamber, piston seals seal the piston against the cylinder barrel. Due to the wide range of requirements in hydraulic applications (such as pressure, pressure peaks, sliding speeds, temperatures, and process media) choosing the right piston seal is very important. The Dichtomatik product brand portfolio offers a wide range of elastomer and thermoplastic seals, such as the K, KK, KNA, KPOR, or N series. The piston seals are used for hydraulic cylinders in mobile hydraulics, agricultural machinery, construction machinery and presses.
