Dixie EMS 5080 Heavy Duty Metal Oxygen Cylinder Wrench/Key with Chain

Sturdy unlike the plastic ones. This one I do not foresee it breaking on you. I use these very often as an OR nurse and I wanted to have an extra of my own that I could keep in my pocket. Not disappointed at all!

works great on my roller style 3ft oxygen cylinder. It is a lot stronger than the plastic ones i had before for sure. Cost a little more but well worth it. The metal lanyard is a nice touch too. i will never loose it

If you're tired of the cheap plastic oxygen tank wrenches that crack, break, or snap, grab one of these. All metal, but light weight and durable.

A little pricey compared to alternatives, but once seeing it, I knew I made the right choice. If you are on O2, this will save you grief.

Haven’t used it yet but it seems good. It is light weight but definetly well made and not flimsy. So we’lll see. Got this for EMT stuff lol

I love this tool. I was so tired of having to replace the plastic ones for my oxygen tanks. I bought 2 so I can have one in my car and another in my purse.

This tool seems more durable than the plastic ones my oxygen supplier gives me. I keep it in my car as a spare. It has a metal cable so you can leash it to the regulator. This wrench would probably be well suited for professionals due to its heavy duty construction.

It fits a standard tanks. My plastic key was starting to wear a little and this oxygen key comes with a metal wire I can clip onto a carabiner on my EMT work belt. I put the key in my back pocket and I don’t feel it anymore. No complaints.
