ABSTRACT:
A closure assembly is provided for high pressure applications. It includes a hollow cylindrical member having a beveled end for welding to a pressure vehicle and a threaded end for receiving a cap. An annular projection extends from the threaded end and includes a O-ring for sealing purposes. The projection has relatively thin walls which allow it to dilate under pressure and provide an excellent seal.
