This patent describes a metal gasket that has an S-shaped longitudinal section. Metal rings may be fitted into the recesses in the section. It is claimed that the seal ring is not elastically deformed, even under a high compressive load, thus reducing fatigue failures and avoiding potential damage u
the pipe connection work and quality of the connection by eliminating the need to form a flare on the pipe. The pipe joint consists of a flare joint body (1), a cap nut (2) and a stop ring (3). The rounded, pressure-contact sloped surface (32) of the stop ring (3) makes contact, under pressure, with
Change-over valve mechanisms are often assembled on a manifold base which contains a number of fluid inlet and outlet passages. These supply and discharge pressurised fluids from ports on the mechanism through separate pipes. A gasket is usually provided between the manifold base and the change-over
