About the Western M1-540-P Oxygen Pressure Regulator

The Western M1-540-P Oxygen Regulator is part of the Western M1 Series and comes preset to 50 PSI. The regulator has a 90 degree DISS 1240 outlet which makes it easy to connect your oxygen hose. The large 2-inch gauge allows for a more accurate reading of the gas pressure left in the connected oxygen tank. The CGA540 inlet is nut and nipple style and will require a wrench to tighten or loosen. If you need this regulator but prefer a CGA540 hand tight wheel, visit the Western M1-540-PH page. 

The Western m1540p is a durable long lasting product that comes with a standard 6 year limited manufacturer warranty.

Oxygen regulators help regulate the flow of gas from the source to the device being connected to the regulator, such as a flowmeter or oxygen hose. The Western Medica M1-540-P regulators are some of the most reliable in the industry and can be found in many facilities across the country. Some of the M1 series regulators come preset with an outlet pressure of 50 PSI which does not allow the user to make any adjustments. This preset option is sometimes preferred as it keeps the delivery pressure constant at all times.
