7.5~11.5 PSI Pressure Burst Disc on 2.75" CF Flange

Low Pressure Burst Disc on 2.75" CF Flange

Low Pressure Burst Disc on a 2.75" 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 7.5 to 11.5 psi (gauge). Mounted on an industry standard 2.75" CF flange, these low-pressure burst discs provide an instant pressure-relief path for ultrahigh vacuum (UHV) vessel's experiencing accidental over-pressurization.
