MB™ , MBV™, AMB™, AMBV™ Disk Specifications Minimum/Maximum Pressure with Rating at 72° (22°C)
Example: If a Saf-T-Graf MB type disk is ordered with a 29 psig (2 bar) burst pressure, it will burst between 27.5 psig (1.9 bar) and 30.5 psig (2.1 bar). For reduced tolerances contact BS&B.

Armor is recommended for all graphite disks for added safety and elimination of breakage during installation. Armor consists of a steel ring encircling the outside diameter of the graphite rupture disk.
Armor is standard on disks with burst pressures in excess of 150 psig or to fit ANSI Class 300 / 600 flanges. Carbon steel armor is standard with 300 series stainless steel as an option. Armor is recommended for applications where lateral blow out / loss of containment represents a safety concern.
Armor for disks sizes shown when rated pressures equal to or exceed values in the below chart.
MB™, IMB™, and IMBL™ type impregnated graphite disks offer low burst pressures and excellent corrosion resistance
