Metal Jacketed gaskets (MJ)
Metal jacketed gaskets (either double jacketed or single jacketed) are comprise of a soft filler material encapsulated by metal.
The filler material ensures elastic rebound, while the metal jacket provides the actual seal. It also protects the filler material from pressure, fluctuating temperatures and corrosion. Several types of material are available for making the best seal under specific conditions.
MJ gaskets are traditionally used for heat exchangers, pumps and valves. The elastic rebound and reusability of these gaskets is limited. They require machined flange surfaces and high bolt torque to provide an effective seal.
