Abstract: This invention pertains to a method and apparatus for venting pressure from within a pressurized housing. It incorporates a sealing assembly that is secured within a housing and restrained against a pressurized channel by a nut. By loosening the nut, restraint on the sealing assembly is released thereby allowing fluid from the channel to travel the length of the sealing assembly and exit the housing. Conversely, by tightening the nut, restraint on the sealing assembly is reapplied which blocks the channel once again thereby preventing any more fluid from flowing.
