TAGTR8-8B Oxygen Cylinder Regulator, Green Anodized Aluminum, 0-8 LPM 870 CGA

I use the C size tanks and carry them in a special back pack (available here on Amazon) I need 2.5 liter flow when I hit an up hill while walking. A 2L flow is not enough and 3L makes the tank go too fast. I never even noticed until I started walking and needed the 2.5, litre that many regulators jump from 1.5 to 2 then up to 3. If you do not need flow over 8 liters, this regulator that ends at 8 liter gives you much better control at the low end.

Regulator broke after 15 months even though it was not in constant use. This was disappointing. It may be an isolated problem because the regulator appears to be same as that provided with oxygen tanks by my home medical equipment supplier.

This value seems to leak at the valve where you attach your air hose. I think a larger valve should be used and possibly Teflon tape. Outside of this issue I am grateful to have found this product!
