The most basic type of semi-metallic gasket has a compressible insert enclosed within metallic jacket. The insert material forces the metal to deform to suit the flange surface and effect a seal.
Metal jacketed gaskets are commonly used in heat exchangers though are often replaced by Maxiprofile style gaskets. Metal jacketed gaskets can be manufactured with a number of metals and high temperature fillers.
