Low Pressure Burst Disc on 1.33" CF Flange
Low Pressure Burst Disc on 1.33" CF Flange 

Low Pressure Burst Disc mounted on a 1.33" CF Flange

Accu-Glass low-pressure burst discs have a stress pattern scored right into their 316 stainless steel foil diaphragm. They're designed with a large 1.93 square-inch deflection area that will rupture when a vacuum vessel's internal pressure has reached 9 to 11.5 psi (gauge). Mounted on an industry standard 1.33" CF flange, these low-pressure burst discs provide an instant pressure-relief path for ultrahigh vacuum (UHV) vessel's experiencing accidental over-pressurization.
