Abstract
A rupture disk which is welded or brazed to a relatively massive or robust ring member integrally attached to the remainder of the body by an isolating member of reduced cross-sectional thickness. The upper part of the tubular body is attached by welding or brazing to the lower half of the body at a flange which extends outwardly from the mounting member. This eliminates the need for compressive forces to effect a seal, and one or two sources of potential leakage and setpoint shift (assembly force) are thereby eliminated.
