Ring type Joint Gaskets are designed to seal by "initial line contact" or wedging action between the mating flange and the gasket. By applying pressure on the seal interface through bolt force, the softer metal of the gasket flows into the microfine structure of the harder flange material, creating a very tight and efficient seal.
Octagonal Type
More accurate in dimensions and surface finish than oval type because it consists of straight surfaces only. A Higher torque load is required to flow the gasket material into imperfections of the flange facings.These gaskets comply with ASME B-16.20.
Oval Type
The contact face is in oval shape. It provides a high reliabililty seal. These gaskets comply with ASME B-16.20.
