PTFE lip seals, which can be pressurized on one side, as rod or piston seals

Forseal seals from Freudenberg Sealing Technologies are groove-ring-like seals for pistons and rods that can be pressurized on one side. In their basic design, they consist of an especially stressable PTFE seal and a metal spring as a static pretensioning element for the seal lip. As a customer-specific solution, Forseal seals can be oriented to precise requirements for materials and designs.

With its nearly universal resistance and a spring- assisted seal design, Forseal permits optimal, long-lasting functional reliability in a wide range of applications – especially under extreme loads. The basic design consists of an especially stressable PTFE seal and a metal spring as a static pretensioning element for the seal lip. In case of heat expansion, this guarantees the optimum contact pressure if it cannot be provided by the system pressure during operation. Thanks to this combination, Forseal shows an extraordinary capacity to handle exposures to aggressive media, thermal influences as well as friction and abrasion. This makes it an especially reliable and cost-effective sealing approach for demanding requirements.
