Features Specifications:Sell jacketed gasket (double jacketed gasket,metal jacketed gasket) Jacketed Gasket Jacketed Gasket excellent sealing and protects the filler against pressure conditions, fluctuating temperatures and corrosion. Specification: Description:QS Double Jacketed Gasket (DJG) is made from graphite, ceramic, non-asbestos etc. filler covered with thin metal jacket, such as stainless steel, carbon steel, copper etc. By their sealing efficiently, provide outstanding resilience, while the metal jacket guarantees excellent sealing and protects the filler against pressure conditions, fluctuating temperatures and corrosion 3061DJ Double Jacketed Plain Gasket  3061DC Double Jacketed corrugated Gasket  3061S DJG with Special Shape APPLICATION: QS DJG is particularly suitable for sealing flat surfaces of heat exchanges, gas pipes, cast iron flanges, cylinder heads of engines as well as for boilers and other vessels. By their sealing efficiently, provided by exerting strong pressure on circular rimes of the flanges, metal-jacketed gaskets can stand up to 30% deviation from the initial thickness, which is very useful in case of irregular or faulty flange rims. The chemical compatibility of the metal and the medium being sealed should be considered. MATERIAL:  Metal material  Din Material NO.
