Piston cups provide a mechanical sealing surface on the edge of hydraulic and pneumatic piston heads, plungers, and rams. They can include a hole in the center of the cup.

Piston cups provide efficient sealing and pressure containment across various industries. These seals fit onto piston ends, expanding under pressure to prevent leaks. Their adaptability to diverse pressures, temperatures, and fluids makes them key for the reliable operation of systems requiring precise fluid control.
