O-Rings from Freudenberg Sealing Technologies: Diverse usage options

Continuous circular sealing rings with a circular cross-section; these are O-Rings. A classic in the world of seals which, as highly versatile products, can be used in a multitude of ways. In most cases, the exceptionally reliable sealing O-Rings from Freudenberg Sealing Technologies are used for the static sealing of idling machine parts against liquids and gases, as required in water valves, air conditioning systems, vehicle engines and dental drills. O-Rings are also ideal as dynamic sealing elements, however, including for piston or rod seals in hydraulics.

O-Rings: Versatile materials to meet every requirement

Freudenberg Sealing Technologies utilises a wide range of materials to ensure that the O-Rings meet the needs in their equally diverse range of applications. For example, FEP/PFA-coated O-Rings combine the excellent chemical resistance of PTFE with the elastic behaviour of an elastomer. These O-Rings are used when the chemical resistance of an elastomer O-Ring made from PTFE is inadequate because the seal also needs to provide elastic properties. Depending on its field of application, the O-Ring must be resistant to ozone, swelling and high temperatures. Other requirements demand chemical stability, pressure resistance or flexibility at cold temperatures. The food industry, in turn, demands FDA conformity, i.e. food safe. All these varied requirements are met by O-Rings from Freudenberg Sealing Technologies.

O-Rings: Reduced abrasion, long service life

Depending on the application, Freudenberg Sealing Technologies offers O-Rings which are coated with suitable powders, special greases, emulsions or varnishes. This allows this all-rounder product to be optimised for the use in question. Thanks to reduced abrasion and wear, this ensures a significantly longer service life. Depending on its field of application, an O-Ring must be resistant to ozone, swelling and high temperatures. Other requirements demand chemical stability, pressure resistance or flexibility at cold temperatures. The food industry, in turn, demands FDA conformity, i.e. food safe. All these varied requirements are met by O-Rings from Freudenberg Sealing Technologies.

Range of O-Rings: Also available in custom designs

Freudenberg Sealing Technologies offers a large range of O-Rings for a wide variety of applications, including in special designs and with a custom protective layer.
