What is a Metal seal?

Metal seals are metal gaskets that demonstrate airtightness under more severe conditions than O-rings, which are generally made of resin or rubber materials. Sealing performance is maintained and demonstrated in a high temperature, extremely low temperature, high pressure, and ultra-high vacuum environment that is higher than the conditions that the resin or rubber material rings and gaskets can withstand. Metal seals come in a wide variety of cross-sectional shapes, structures, and materials. When using a metal seal, it is necessary to carefully consider the sealing structure, environmental conditions, required specifications, and the fluid that comes into contact with it.
