AireMed Oxygen Regulator 0-15LPM, CGA-870 Gauge Flow Rate – Includes Wrench Key, 5 Brass Yoke Washer Seals, and 2 Oxygen Tubing Swivel Connectors - Ergonomic Handle Design – Silver

My oxygen provider will only give me one regulator for tanks and I don't like the idea of having no backup when oxygen is a life-sustaining product. This is a device that fits on top of an oxygen tank so that it regulates the flow rate that oxygen comes out of the tank for the user. Without a regulator, there is no way to use the oxygen. So it's a pretty important piece of equipment. I am grateful that this was available and at a reasonable price since I've seen some of them cost three figures. This regulator also had a bonus of some extra equipment, such as a "key" (a wrench like device for opening the tank once the regulator is on), some swivel connectors for the cannulas and some more washers for the regulator. The washer is dry out from time to time and when that happens oxygen leaks out of the tank so it's really important to have some extra washers on hand in case of an emergency. This particular regulator goes up to 15 liters of continuous flow. The settings are 0 (off), 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 15. I use 8 liters and I wish that the numbers above that were consecutive and not jumping and skipping numbers, but that does seem to be typical for these regulators. The higher your setting, the faster you go through the oxygen.

Works great!!

This regulator fits the O2 bottle well and seals correctly.

Fits the valve like you'd want them to and works as it should. Build quality of it seems to be very nice as well. Overall just a great little product!

Did not fit the style of my current oxygen tanks. The two prongs that fit to the tanks are too short and oxygen hose barb is also too small.

All the parts operate as they should. No issues found with sealing or assembling the regulator. Seems to be of good quality.

The seal washers have to be changed too often

It appears to be a high quality regulator. I don't have experience with the sealing surfaces but the build appears nice.
