O-Rings are among the sealing classics par excellence. Primarily used for static sealing of inactive machinery components against liquids and gases. Special solutions and special forms from Freudenberg Sealing Technologies are also suitable as dynamic sealing elements, e.g. as piston or rod seals in the hydraulic system.

Are you looking for an O-ring and the corresponding installation space?
FST’s innovative, web-based O-ring configurator sets improved standards as an auxiliary application for O-ring selection. The goal of this online tool is to select an optimal combination of O-ring and installation space to ensure a reliable seal. Unlike other O-ring configuration programs, the calculation analyses and target value recommendations are based on the current ISO 3601 and other international O-ring standards.
