iGuerburn Small Heavy Duty Metal Oxygen Cylinder Tank Wrench O2 Key with Lanyard Cable Chain for CGA 870 Standard Post Valves for Sizes M2 A(M4) B(M6) ML6 C(M9) D(M15) JD(M22) and E(M24)

This is a backpack for my husband’s oxygen portable cylinder. We were pleased with the design, weight and quality.

Venia muy bien empacada y con todos sus accesorios

A basic tool, this device is well made of metal and will make a long lasting tool for compressed gas.

It is what it is. It’s heavy duty. Brings my scrubs down so beware of that. But it will last forever if I don’t lose it.

Key is great and looks as it does in the pic but it does not come with the metal string to attach to O2 tank.

The wrench is much sturdier than the standard plastic ones you receive from your medical supply company. They include a small screw driver so you can attach the braided metal cord. I use the cord with my key holder in my back pack that I use with my oxygen tank. Being metal means I don't have to worry about it breaking while I'm out of the house and need to switch tanks or turn off the current tank when I get home. Overall the wrench is definitely a worth while buy for anyone permanently on oxygen.,

I like that it is nickel and therefore durable. But it is so heavy I can’t really have it on my keychain. So I still have a plastic one there.You can’t have steel things on an O2 tank so the cable is a No-no. I wish the cable provided was a piece of twill tape or paracord instead.

Standard use Oxygen tanks, turning/opening canister. Key. It came with a "Leash" on a flexible cable which is handy as to Not Misplace it. I keep one in my Nursing Bag incase I need it. Sometimes these go missing in medical work environments. I'm very satisfied with this product.
