Piston Cup Seals


Piston Cup seals are used on rams or plungers in both hydraulic and pneumatic applications.

Basic Piston Cup Seals (CUP) are typically used in low pressure pneumatic and hydraulic cylinders. Fabric reinforced Piston Cups (CRF) are used in applications where tolerable pressures up to 800 PSI can be sealed.

Piston Cups are useful in applications where large extrusion gaps exist.

Ludowici also stock a range of one piece piston cups that can replace complete piston assemblies are are bolted directly to the cylinder Rod. These are designed to work in both pneumatic and low pressure hydraulic applications.
