Piston Cup Seals
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. We offer a wide range of elastomer and thermoplastic seals, such as the K, KK, KNA, KPOR, or N series. Piston seals are used in hydraulic cylinders in mobile hydraulics, agricultural machinery, construction machinery, presses and in process applications.
