Special Sealing Products

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.

Clamp seals from Freudenberg Sealing Technologies guarantee a fast and especially secure pipe connection in continually operated equipment. They are nonetheless easy to separate and stand out for their especially easy installation.

Even if machine elements under pressure are firmly bolted to one another, there is still a so-called static seal gap that must be sealed. O-Rings – or O-Rings with back rings for improved extrusion stability – are most commonly used. If the requirements are more specialized, one-piece sealing elements made of polyurethane come into use.
