Metal Seals (O ring – C ring)

METAL SEALING

Metal O-rings have been developed as a secure sealing of gases or liquids. They even can be usedin case of extreme conditions. These static and metallic sealing elements can be applied in rangesof ultrahigh vacuum and up to a pressure of 6800 bar. They are suitable in case of continuous temperatures from 269 degrees centigrade below zero up to 980 degrees centigrade above zero and resistant to radioactive radiation, chlorides, corrosion and other aggressive influences.

Metal C-rings are static sealing elements for machines and installations with high requirements. Metal C-rings are considerably more elastic than metal O-rings and other metal seals.

The sealing is secured by means of the spring-back of the metal C-rings, as movements inside the flanged joint (in extreme case flange removal) have to be taken into account. The prestress / deformation is approx. a 20% of the ring height.
