- Seals for high-temperature to cryogenic environments, such as sections close to exhaust gas
- Provides high sealing performance with low tightening loads due to springiness not exhibited by metal O-rings.
- Suitable for mass production since metal seals are press-molded.

Feature

Metal seals meet the need for high-temperature, cryogenic and high-pressure applications where rubber gaskets are not usable. They are used under severe conditions, as in sections close to exhaust gas.

 

 Elasticity produced by a C-shaped cross section and the equipment pressure that works from within the C shape to expand pressure surfaces maintain the sealing characteristics (self-following), ensuring sealing performance stably at high pressures. The clamp load required for metal seals is not more than half that for metal O-rings. This contributes to improved ease of assembly, reduced loading on flanges and enhancing weight reduction.

 

Metal seals are suitable for mass production since they are press-molded. With no seams such as those caused by welding, they provides stable sealing performance.
