Welcome to Mountain High’s new line up of CGA-540 pressure regulators!
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.
