Abstract: A pressure vessel includes a shell, a liner, and a boss. The liner is positioned within the shell and defines the interior environment. The boss is located at a first interface between the shell and the liner. The boss includes a cavity and a venting structure located in the cavity. The cavity is located at a second interface between the liner and the boss, and the cavity is located at an interior surface of the boss in communication with the interior environment. A gas vent path is defined from the first interface, through the venting structure, and into the interior environment of the pressure vessel. The disclosure also describes a boss for a pressure vessel and a method of manufacturing the boss. The boss includes a port, a flange, a cavity and a gas venting structure. The cavity and gas venting structure are located on an interior of the flange.
