Oxygen & Acetylene setup advice

I get my gas from a local supplier. All good suggestions and I'll ask them. I said different types because I thought the cylinders had different fittings for the gauges. I was specifically looking at the small portable.

The really small ones yes. I believe there are 3 different fittings. The "suitcase" tanks acet is one size, the O2 are all the same. There is a larger --I think it's called a "B" acetylene, uses a second type fitting. Most any acet tank that is large enough "for a cart" uses from there on up are the same "larger" fitting. If you have gauges that fit the larger "cart" tanks you can get acet adapters for the other two

I was mostly right LOL: NOTE: The drawing is not to scale, they are not "stubby" these are the ones you have seen.
