Harris 425 Series Medical Air Regulator
The Harris 425 Series is a single-stage cylinder regulator designed for medical air delivery. It provides an outlet pressure range of 0 to 125 psig with a maximum inlet gauge pressure of 4,000 psig. The unit features a chrome-plated brass body and a neoprene diaphragm for reliable operation in industrial and medical gas applications.
Verify CGA 346 and Connection Compatibility
Before ordering, confirm your cylinder uses a CGA 346 valve outlet for breathing air service. The regulator inlet is a male NGO connection sized .825 in.-14, while the outlet is a male UNF connection sized 9/16 in.-18. Ensure your downstream equipment matches these thread specifications and that the single-stage design suits your pressure stability requirements.
Suits Fixed Medical Air Supply Points
This regulator suits facilities needing a dedicated medical air control point with a 2.75 inch gauge for clear pressure monitoring. It is not intended for users requiring multi-stage pressure regulation for ultra-stable flow or for gas types other than breathing air. Buyers needing different CGA fittings or outlet thread standards should select an alternative model.

Questions about this item
Does the Harris 425 Series regulator ship with a hose or fittings, or must they be purchased separately?
The regulator has a CGA 346 male inlet and a 9/16 in.-18 UNF male outlet; hose and mating fittings are not included and must be sourced separately.
How does the 0-125 psig outlet range suit medical air delivery compared with higher-pressure models?
The 125 psig maximum outlet is designed for low-pressure breathing air systems; higher-pressure models would exceed the safe delivery pressure for this application.
What does the 2.75 in. gauge diameter mean for reading outlet pressure on the machine?
The 2.75 in. dial provides a clear, direct reading of the 0-125 psig outlet pressure without needing a separate gauge.
