Metal seal for extremely high and low temperatures where a rubber gasket cannot be used. Therefore ECOCS^® was developed to be used in harsh environments like hot exhaust gas conditions. The seal also offers a stable seal function in high pressure conditions due to the flexibility that comes from its sectional "C" shape.

The shape also contributes to the improved ease of assembly and reduced load onto flange and weight saving, since the clamp load of ECOCS^® is roughly half of the clamp load of a metal O-ring. Since ECOCS^® is produced as a stamped part, there is no welding joint. This improves the sealing function significantly.
