Western Medica brand regulators are some of the most well-known in the healthcare industry and used in many facilities. Regulators are specialty medical devices used to help regulate the flow of gas from the source to the device being connected to the regulator, such as a flowmeter or gas hose. The M1 Series regulators are single-stage regulators that allow for the reduction of delivery pressure, also referred to as outlet pressure, in one step. The M1 series also offers preset regulators that are set permanently to an outlet pressure of 50 PSI. The preset regulator is used by many facilities as it keeps the regulator’s delivery pressure consistent during use.

The M1-540-PH Oxygen regulator by Western comes preset to 50 PSI. The CGA540 hand tight wheel makes it easy to tighten and loosen the inlet connection without the use of a wrench. The M1-540-PH also features a 90 degree DISS 1240 outlet connection allowing for easy connection to an oxygen hose. The large 2-inch gauge allows for a more accurate reading of the gas pressure left in your oxygen tank. If you’re in need of a regulator with the same specs but prefer a CGA540 nut and nipple inlet connection (no hand tight wheel), visit the Western M1-540-P page. 

Western Medica brand regulators come with a 6 year limited manufacturer warranty.
