What is the pressure rating of an oxygen cylinder valve rupture disk?

The pressure rating of an oxygen cylinder valve rupture disk is crucial for safety and operational integrity in environments where high pressures are common. A rating of 4200 psi reflects the maximum pressure at which the rupture disk is designed to operate safely. At this pressure, the rupture disk acts as a safety device that protects the cylinder and the connected systems from catastrophic failure.

When pressure in the cylinder exceeds this rating, the rupture disk is designed to fail in a controlled manner, thereby relieving excess pressure and preventing potential explosions or ruptures that could occur if the cylinder were to become over-pressurized. This safety feature is pivotal in oxygen systems because oxygen supports combustion, and any uncontrolled release of high-pressure oxygen could lead to fire hazards.

The other pressure ratings, while relevant for other applications or gas types, do not pertain to the widely accepted standard for oxygen cylinder valve rupture disks.
