fortis fasteners Germany fortis model fortis price

fortis fasteners are made by integrally bonding and vulcanizing a rubber ring and a metal ring. They are sealing rings used to seal threaded and flange connections, consisting of a metal ring and a rubber gasket. The metal ring is treated for rust prevention, and the rubber ring is typically made of oil-resistant nitrile rubber or fluororubber. Combined gaskets are available in metric and imperial sizes, with standards specifying the combination form of the metal gasket and rubber. Combined sealing gaskets are used for sealing threaded pipe fittings and plugs. They are generally used together with ferrule-type pipe fittings to seal oil ports, primarily for the end faces of threaded connections on hydraulic valve pipe fittings.
