hkm fasteners, Germany hkm models, hkm prices

hkm fasteners are made by bonding and vulcanizing a rubber ring and a metal ring into a single unit. 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 typically made of oil-resistant nitrile rubber or fluororubber. Combined gaskets are available in metric and imperial sizes, with standards specifying the combination of metal and rubber. Combined sealing gaskets are used for sealing threaded pipe fittings and plugs. They are generally used with compression-type pipe fittings to seal oil ports, primarily for static face sealing at the threaded connections of hydraulic valve pipe fittings.
