Piston Seals

PolyGobal’s piston seals are utilised in both pneumatic and hydraulic applications to ensure system pressure is maintained along one side of the piston. Effective piston seals successfully facilitate the application of maximised mechanical effort in the movement of the piston along the cylinder and optimise performance. Piston seals ensure efficient performance.


As with PolyGlobal’s rod seals, both single and double acting profiles are available to ensure effective sealing where pressure is applied in both directions. A range of standard and bespoke profiles to optimise sealing performance in every application.
