Amazon Regulators vs Medical Supply Regulators


Recommended Posts

Hello all. Anyone have any positive or negative experiences they are wiling to share regarding cheap O2 regulators from Amazon? I am looking to purchase one and want to get it right the first time. I primarily use E tanks since that's all I can get these days. 

My O2 supplier charges $125 for a regulator through them or $75/month to rent one. 

Thanks!

I’ve used a few cheaper regulators and found that you get what you pay for. Some worked fine for a while but had flow issues later. It’s worth checking reviews and ensuring the regulator is easy to adjust. Look for ones with warranties or easy replacements.

For our uses, I like the low cost of the Amazon units. If anyone asks, this is what I recommend. Now if I were an EMT, would I want to carry one on the truck? Probably not, but for our use I think they are fine. The low price gets someone with limited resources a 25LPM regulator for minimal outlay. 

I have a WT Farley too. Great, well-made unit with a 40LPM option but they cost a bit more. 

The only regulator I've had trouble with was a one I purchased on eBay.....the yoke bent after a few years of use and wouldn't stay sealed to the tank outlet. I robbed a couple parts off it and in the trash it went. I figure I got more than 20 bucks worth of use out of it. 

With any regulator, keep spare seals around. You'll need them eventually.

...my favorite O2 shop tech gave me a bag of these and said "don't be afraid to change frequently, you don't want failure at the worst possible time". same dude "loaned" me (wink wink) an m60 tank reg (different than e-tank) which i still have..."return when you don't need anymore" he said. for a clusterhead that meant never. also have several spare e-tank regs bought from Amazon...Medline i think...never had a single problem. ALWAYS have a spare...it's really cheap insurance that you won't need until you REALLY do.
