MH Oxygen Regulators are constant-pressure regulators calibrated to deliver 15 -20 psig of dynamic pressure. Regulators are offered in CGA-540 (US standard) and DIN-477 (European standard). All MH regulators are designed and built by us at Mountain High allowing us to service and make any repairs the might be required.

XCR and XCP Single Outlet Regulators

The XCR and XCP series of regulators are single-outlet. These regulators feature the Push-to-Connect fitting system for 4 mm and 6 mm polyurethane tubing. The standard issue with our XCR and EDS single-unit system packages is the 00REG-1033-00 Regulator. The axial outlet versions are available in CGA-540 & DIN-477 with built-in cylinder pressure gauges. The XCR regulators connect directly to the refill/service-port of our oxygen cylinder with a CGA-540 valve. All single outlet regulators can be made into a 2-port regulator by adding a splitter.

Four-port XCP Regulators

For delivery to up to four passengers, this piston-type gauged oxygen regulator design is known for its ruggedness and flawless operation, even in an extreme environment. Calibrated operation is ensured in a wide range of inlet pressures, temperatures and shock-vibrations.
NOTE: We do not manufacture a 2-port regulator as we found the cost of manufacturing to be the same. This option also allow expansion at a later date without having to purchase a new regulator with additional ports.
All not used ports have a one way valve and are sealed when not in use.

In-line Reducing Regulator

The EDS-ILR oxygen stabilizing regulator allows you to operate EDS O2D1 or EDS -O2D2 units from an oxygen source with high service pressure, such as an aircraft with a built-in oxygen system. The EDS-ILR Regulator can be ordered with the most common OEM type connectors for direct ‘Plug-n-Fly’ with your aircraft type. (See below) Call for us for OEM options.
