Metal Jacketed Gaskets, as the name suggests, consist of a metallic outer shell with either a metallic or non-metallic asbestos free filler. The filler material gives the gasket resilience, while the metal jacket protects the filler and resists pressures, temperatures and corrosion.
Metal Jacketed gaskets are available in a wide range of sizes and configurations. They are traditionally used for heat exchanger applications, pumps and valves, however the resilience and recovery properties of these gaskets are limited. Metal Jacketed gaskets require smooth flange surface finishes, high bolt loads and flange flatness in order to seal effectively.
Metal Jacketed gaskets are divided into four main categories: Double Jacketed Gaskets, French-Type Gaskets, Single Jacketed Gaskets and Solid Corrugated Metal Gaskets.
