Flexitallic Products Type Document: Literature Product: Metal Jacketed Gaskets Metal Jacketed Gaskets, as the name suggests, comprise 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. A wide range of materials are available to suit specific temperature and corrosive conditions. Metallic: Aluminum Brass Copper Soft Iron Stainless Steel MonelÆÊ NickelÆÊ InconelÆÊ (Other materials on request) Non-Metallic: Non-asbestos Millboard PTFE FlexicarbÆÊ CeramicÆÊ Metal Jacketed Gaskets are manufactured using hand made techniques, and 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 exacting conditions of flange surface finish, high bolt loads, and flange flatness in order to effect a seal. SINGLE JACKETED GASKETS The filler material is enclosed in a metal jacket which covers the inside and outside diameter of the gasket. Style 120 has one of its contact surfaces covered and is ideally suited for comparatively narrow flange widths in circular and non-circular configurations. Style 124 is an overlapped Single Jacketed Gasket, where the filler is completely enclosed on the inside and outside diameters and on both contact surfaces. Style 124 is more suited for high temperature applications of narrow flange widths. Typical low pressure applications include boilers, compressors, pumps, and diesel and gasoline engines. Style 120 is not recommended for standard pipe flanges. Minimum flange width 6.4mm (1/4.). Nominal gasket thickness 3.2mm (1/8.).
