O-rings
With its range of O-rings, Freudenberg Process Seals offers a universal and cost-effective sealing package for any number of applications in the processing industry.
Freudenberg Process Seals O-rings can be made out of almost all elastomer materials, as a standard part in large quantities or customized in small quantities, while meeting all requirements of media stability.
The necessary installation space is very small in comparison to other sealing systems and thus allows constructions that save materials. Even though simple in construction, the O-ring can still be reliably used in a wide range of installation conditions: as a static seal in axial and radial direction or for dynamic applications with translational and/or rotating movements.
