1-Place Axial CGA-540 Gauged Regulator
Regulator, CGA-540 (2G), Single-Stage (Gauged)-CGA-540 (2G) Gauged, 4mm Push-to-Connect outlet port.
-90 deg outlet and 5′ of 4mm feed tube included.


This series of 2101 second generation (2G) of CGA-540 pressure regulators are gauged. We have supplied these 2G pressure regulators with a high pressure port (1/8NPT-F) to allow the installation of a gauge or high pressure flex-fill extension or other installation options.

Internally we have improved the specifications and machining tolerances of these 2G pressure regulators which in turn provides a more constant manufacturing process and long term product performance.

The 2G series of pressure regulators is compatible with all Mountain High portable Pulse Demand or Constant Flow oxygen delivery systems.

Includes 90 degree 4mm outlet fitting - You can remove the straight port and use the 90 degree elbow port instead.

Note: All Mountain High oxygen systems that include a cylinder also include a valve with gauge.  They do not require a regulator with a gauge.  However, a gauged regulator is a nice option when using a cylinder that does not have a gauge.

This item replaces the MH-00REG-1030-00
