In the new version 2.0 the four robust Orings are supplied in HNBR (hydrogenated nitrile) technical material in the recognizable green color. This automotive material is totally compatible with the contact of oil and hydrocarbons and also has a very high resistance to permanent deformation and abrasion. Much more than a simple rubber ring, it adds a highly technical and distinguishable value to the product. Designed for the heaviest off-road use.
