Piston seals

High-quality piston seals for reliable sealing of hydraulic and pneumatic cylinders. They prevent pressure loss, minimize leaks, and ensure controlled pressure buildup and precise piston movement. Available as single- or double-acting piston seals in various profiles, such as groove rings, Glyd rings, compact piston seals, roof-type and pot-type seals—for high sealing performance, low friction, and long service life.
