Regulator, Assy 2G, 2101 series CGA-540 Gauged-Regulator,
CGA-540 (2G), Single-Stage (Gauged) 
CPC Type outlet port (Single)

CGA-540 (2100 series) of pressure regulators are supplied without a pressure gauge as our CGA-540 cylinders all have a pressure gauge installed already. These 2G pressure regulators with a high pressure port (1/8NPT-F) to allow the installation of a high pressure flex-fill extension option, a secondary remote gauge option, or other installation options.

Internally 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.


CGA-540 port for oxygen cylinder and female CPC port for connecting to tubing leading to an MH3 or MH4 Flowmeter.  This regulator has a different connector than the one found on the XCR regulator.  The EDS-XCP-Adapter can be used to connect an EDS-D1 or O2D2 unit to an XCP or FPR regulator.  An EDS-XCP-Adapter is included with every EDS system.


Male CPC Connector
This type of connector can be plugged into  an XCP or FPR regulator
