Metal Flange Gaskets
Spiral Wound Gaskets – is the most common type of metal gasket. Made up of pressure containing rings and metal windings with a sealing material placed between the windings.

Kammprofile Gaskets – For applications requiring high-pressure sealing with a limited amount of low seating stress. Virtually a metal to metal seal. With flexible graphites 98%+ carbon content, the thermal dynamics of the gasket is very similar to the flange.
RTJ Gaskets – Are made for tongue and grove flanges and are literally a metal to metal seal. Typically manufactured to API 6A for wellhead equipment. They also comply with ASME B16.20 sizes and ratings. Used in gas and oil exploration for high-pressure applications.
