25LPM Oxygen Regulator CGA-870, Adjustable Flow 0-25 LPM - ASTM G175-03 - Aluminum/Brass, Max Inlet: 3000 PSI, Outlet: 50 PSI - Compact 1.38 inches X 4.65 inches

It works at about 2liter amin normal use .it is either a pass or fail nuff said.

It’s a mini which is important to me, works fine, would recommend seller

works perfect, BUT be aware...no pulse feature and only CONSTANT flow device - eats up oxygen tank even full, like my old 1969 GTX with a 426 Hemi in it and two four barrel carbs (4 mpg hwy, 2 mpg city - and if you put your foot all ther way down, you got 30 miles out of a 27 gallon tank

Been a few months, we thought the plastic would have broken,but its been holding up well.

Nice regulator, used for a stronger shot of oxygen when needed, I bought 2 more

Nice to have more than one oxygen tank set up in case of an emergency

This is just what we needed to replace a broken regulator on my son's oxygen tank. It works exactly as it should and is a little smaller than ones we have used in the past. This is great for us as this tank gets carried all over the place in his emergency bag -- the explanation for how the previous one got broken! I'm hopeful that the reduced size will make it less likely to get banged around and damaged. So far so good!

Good quality
