Resumo‘Helicoflex’ is a new type of flexible and elastic metal 0-ring. In this paper relations between sealing performance and the condition of the sealing surfaces are investigated for the Helicoflex gasket. Two kinds of sealing mechanism were found according to the surface conditions of the flange. In particular, when the surface of flange is superfinished, the soft metal sheet of the Helicoflex in contact with flange surface flows in the gap between elastic core and flange surface as the flanges are tightened. The surface of the gasket in contact with flange takes up the same superfinish by flowing. This is a new concept of sealing by elastic metal gasket.
