O-ring seal / metallic

O-ring seal / metallic
GFD metal-O rings are produced of metal tubes or solid wire material. The material is shaped and welded to rings or other figurations. The O-ring consists of stainless steel or other alloys and can be electroplated with silver, cooper, indium, nickel, gold, lead or other metals or can be coated with Teflon*). The flowing of the coating material improves the sealing especially under high pressure and / or vacuum. With conventional flanged joints many technical data, from which only very few are precisely available during the design state, have to be known for the calculation. Also the values for the rigidity of the flange, the screws etc. have to be available. The consequence are extensive calculations with imprecise or assumed values and the involved disadvantages.
