http://www.gasket-china.com------Graphite Spiral Â wound Gasket with inner ring and outer ring CGI.Spiral wound gasket (SWG) consists of a thin metallic strip and soft non-metallic filler that are simultaneously wound on a rotating mandrel. The metal hoop is pre-formed with a V or W shaped profile,Website:http://www.gasket-china.com, which allows the gasket to act as a spring between the flanges. Further, the hoop provides the basic structural element for the gasket while the non-metal filler material seals small imperfections on the flange surfaces. Depend on its excellent compression resilient
