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.).

Style 124 Style 120 DOUBLE JACKETED GASKETS The filler material is completely enclosed by a two piece metal jacket, which covers both the inside and outside diameters and both contact surfaces. Style 126 is similar to style Style 123 with the exception that the metal jacket is formed from a corrugated jacket providing better resilience than the Style 123, since the corrugations form multi-seals across the flange sealing face. Style 127 is a double shell gasket constructed of two reversed wrap-round shells. This provides superior flange support and handleability and provides better...

SOLID CORRUGATED METAL GASKETS As the name suggests, the solid corrugated metal gasket is comprised solely of metal and does not contain any non-metallic fillers in its construction. The temperature limitation of the gasket is therefore only effected by the metal selected. The corrugations provide multi-seals across the face of the gasket and inherent resilience. A minimum of three corrugations is recommended and gasket thickness is approximately 50% of the corrugation pitch. Pitch corrugations can be 3.2mm (1/8.), 4.8mm (3/16.) or 6.4mm (1/4.). Typically used for high temperature...
