Metal Jacketed and Double Jacketed (DJ) Gaskets

Semi-Metallic Gaskets » Metal Jacketed and Double Jacketed (DJ) Gaskets

Metal Jacketed Gaskets and Double Jacketed Gaskets (DJ) are an older but proven technology. Metal Jacketed gaskets have an outer metal casing around a soft gasket core. DJ gaskets were originally designed for heat exchangers. Variations have been produced over the years and many different styles exist. For an improved technology over DJ gaskets, please see the Kammprofile Gasket and CHANGE Gasket on the Munaco website or contact Munaco for more information.
