​​​​​​​Piston seals maintain sealing contact between the piston bore and the cylinder. The moving piston rod creates high pressure on the piston seal, which increases the contact forces between the seal and the cylinder surface. For this reason, the surface properties of the sealing surfaces are crucial for proper sealing performance. We offer a wide range of materials including thermoplastic polyurethanes (TPU), polytetrafluoroethylene (PTFE), polyamide (PA) and nitrile rubber (NBR).
