As the name suggests, the metal jacketed gasket consists of a metal shell with a non-metallic filler.

　　The filling material gives the gasket elasticity, while the metal sheath protects the filling and resists pressure, temperature and corrosion.

　　Metal jacketed gaskets are available in a variety of sizes and configurations.

　　Traditionally, Spiral Wound Gaskets For Sale are used for heat exchangers, pumps, and valves. Although the resilience and recovery properties of these gaskets are limited. In order to effectively seal, Metal Jacketed Gaskets Manufacturers' metal jacketed gaskets require smooth flange surface finish, high bolt load, and flange flatness.

　　Single sandwich gasket

　　The filler material is enclosed in a metal sheath, which covers the inner and outer diameters of the gasket. Typically used in low-pressure applications, including boilers, compressors, pumps, and diesel and gasoline engines.

　　Minimum gasket width: 6.4 mm (1/4 inch). Standard gasket thickness: 3.2 mm (1/8 inch)

　　Style 120

　　One of the contact surfaces of Type 120 is covered, which is ideal for relatively narrow flange widths in circular and non-circular configurations. It is not recommended to use it for standard pipe flanges.

　　Style 124

　　Type 124 is an overlapping single-jacket gasket in which the filler is completely enclosed on the inner and outer diameters and two contact surfaces. It is suitable for high-temperature applications with narrow flange widths.

　　Double sandwich gasket

　　If there are enough bolts to secure the washers, double-jacket washers can be used in boiler and heat exchanger applications. They are designed for high-pressure and high-temperature applications up to ANSI 900.

　　Depending on the diameter, the width of the gasket can be reduced to 8 mm (5/16 inch). It is also possible to produce very large gasket diameters. The standard gasket thickness is 3.2 mm (1/8 inch).

　　Gaskets can be manufactured with various complex configurations of integral or welded dividers.

　　Type 123

　　The filling material is completely surrounded by a two-piece metal jacket, which covers both the inner diameter and the outer diameter, as well as the two contact surfaces.

　　Type 126

　　Style 126 is similar to Style 123, except that the metal sheath is formed of a corrugated sheath, which provides better resilience than corrugated 123 because the corrugated forms multiple seals on the flange sealing surface.

　　No. 127

　　Type 127 is a double-shell gasket consisting of two inverted surrounding shells. This provides excellent flange support and operability and provides better high-pressure resistance.
