A device designed to reduce and control pressure of oxygen cylinders to a level compatible with the operating system or process. The regulator must handle incoming gas pressure and provide a range of delivery pressures.

Oxygen regulators must be clean and in good working condition. If there is oil, grease, or foreign material on a regulator or other equipment, or if the equipment

is damaged, it must not be used prior to being properly cleaned or serviced by a qualified repair technician. See OXYACETYLENE WELDING and REGULATOR.
