Metal jacketed gaskets are formed by a soft material soul (FM, PTFE, graphite, etc.) coated partially or totally by a ductile metal foil. The quality of materials for the metal jacketed gaskets must be chosen according to the working pressure and the fluid with which it is in contact. Thanks to their understandable structure and light are more fully shown that the metal in pressures and high temperatures.
The metal jacketed gaskets can be manufactured with one or more ribs arranged in different configurations. The metal jacketed gaskets are based on standards such as ASME 16.20 or according to specific customer specifications. The most commonly used for manufacturing metal-plastic joints are materials as metal material: copper, aluminium, AISI 304, 316L, 321, soft iron and as filler material: mineral fiber or graphite.
