XCR-G, 1-place Axial CGA-540 Gauged Regulator

OLD VERSION - See new version here: MH-00REG-2101-04

CGA-540 port for oxygen cylinder and 4 mm port for tubing to EDS
Includes 1 extra o-ring and 5 feet (1.52 m) of red 4 mm O.D. tubing

Includes 90 deg 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.
