sfsb fasteners are formed by the integral bonding and vulcanization of a rubber ring and a metal ring. They are sealing rings used to seal threaded and flange connections. The ring consists of a metal ring and a rubber sealing gasket. The metal ring is treated for rust prevention, and the rubber ring is generally 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, mainly for static face sealing at the threaded connections of hydraulic valve pipe fittings.
