mollificio flli 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. The ring consists of a metal ring and a rubber 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 block oil ports, mainly for hydraulic valve pipe connections.
