Western’s line of regulators are commonly found throughout the medical industry and are known for their durability. These oxygen regulators are used to help regulate the flow of oxygen from the source to the connected device, such as an oxygen hose. Western Medica’s M1 Series regulators are all single-stage regulators, which allows the delivery pressure (or outlet pressure) to be adjusted in one fluid step via the knob on the front of the regulator. 

The Western M1-540-PGH regulator has an adjustable oxygen delivery pressure between 0-100 PSI. It also comes with two large 2-inch display gauges, one that measures the tank/source pressure and the other measures the delivery pressure. The 90 degree DISS 1240 outlet allows you to easily connect a medical oxygen hose. The CGA540 hand tight wheel makes it easy to tighten and loosen the inlet connection without the use of a wrench. If you need this regulator but prefer a CGA540 nut and nipple inlet, visit the Western M1-540-PG page.

Western’s regulators come with a 6 year limited manufacturer warranty.
