Abstract
A thermal release plug for a pressure vessel having a plug well formed in the wall of the vessel. The well contains a circular metal plug member and a low temperature fusible sealant. The well is generally frusto-conical in shape with standoff means to contact the plug at at least three points and thus provide narrow circumferentially disposed arcuate gaps between the plug and the well wall between points of contact. The sealant is fused to the well surface in a furnace under copper brazing conditions.
