Double jacketed Gasket APPLICATION:

Double Jacket Gasket 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. With efficient seal ability, it will exert strong pressure on circular rims 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.
