Solid Flat Metal

Solid flat metal gaskets are usually used where conventional gaskets can not seal the joint due to high temperatures and pressure.
Normally gasket material is softer than flanges or mating surfaces. In this type of gasket, sealing is provided by metal to metal surfaces the sealing surfaces should be carefully aligned and have proper roughness range.
Solid flat metal gaskets can be produced in any shape from plain rings to complex shapes with various corners and holes.
