Yaang's Ring Joint Gaskets are precision machined, metallic sealing rings suitable for high pressure and high temperature applications. RTJ 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 micro-fine structure of the harder flange material, creating a very tight and efficient seal.
