C-ring seal / metallic
The GFD metal C-rings in this product series are static sealing elements, which you can use for machines and installations with high requirements. In addition to this, the metal C-rings are also regarded as more elastic than standard metal O-rings, as well as other metal seals. Note that the pre-stressed forces are approximately one third of the ones for O-rings. However, the pre-stressed forces differentiate, in accordance to the heat, material, treatment and tolerances.The sealing is also secured by means of the spring-back of the metal C-rings, moved inside the flanged joint. The deformation or prestress is approximately 20% of the ring height, while the metal C-rings are available for internal and external pressure or axial thrust. The seal can operate, as the metal C-rings are open towards the thrust face, while the rings are also available with a ring outside diameter ranging from 6.5 mm to an impressive 300 mm.
