Rod Seals

PolyGlobal’s rod seals work to seal along the cylinder. They maintain system pressure on the rod side, and prevent fluid leaking from within the cylinder as the rod reciprocates past it. Often these are the most important aspect of a sealing system, as failing seals lead to failures in performance rather than just inefficiency. . PolyGlobal produces both single and double acting rod seals to ensure effective sealing where pressure is applied in both directions. It offers a range of standard and bespoke profiles to optimise sealing performance in every application.
