API 6A 150LB 304SS Oval Ring Joint Gasket 

RTJ gaskets are designed to seal by “initial line contact” or wedging action between the mating flange and the gasket. It is essential to choose a softer metal of the gaskets while the flange’s material should be harder to make sure the ring type joints can give a very tight and efficient seal after applying pressure on the sealing interface through bolt force. Usually, the ring gaskets are used in oil, petroleum and chemical process fields. As precision machined, metallic sealing rings, ring joints are suitable for high pressure and high-temperature applications.
