Found it.  Try "leaky valve on an acetylene bottle."   

On a side note, what the heck kind of wrench are you suppose to use on an 10cf, MC bottle?

You can get the little square wrench at a welding shops. I think it is Yellow Jacket that makes a nice ratchet wrench that has four sizes on it. That's one more of the tools you can get at Arrow.

The metric adjustable wrench works well in a pinch. 

[sanglant]

these are way over priced,(double what i paid for mine) but they'll work in a pinch.

But you should get and use the little square hole wrench so you don't round your stems off.
