just witnessed this and thought it was funny and wanted to tell you
guys about it. i unscrewed/removed the brass valve off three barbecue
size propane tanks.

How would you seal a slow leak in a 20 Lb propane cannister that's
leaking around the threads in the valve. It seems to be a pretty slow
leak. I can smell it and spotted it with soapy water. Tightening the
valve any more doesn't seem to be an option. I tried that and at the
point that the Barbeque connection was pointing to the rear of the
collar, the threads were squeaking. To turn it any farther would
probably break off the valve.



There's an O ring around the stem, grease it w/ some silicone grease in
the groove before snapping the o ring into place.
He's talking about the joint where the valve screws into the cylinder.
If its a new cylinder take it back(in an open convance) to where he
got it. Otherwise open the valve and vent the gas to the atmosphere
until it is EMPTY!

I had something similar happen to me once.
Turned out it was the retaining collar inside the valve.
It had unscrewed itself a turn or two and would not allow correct seating.
Screwed it back in and everything worked correctly again.

I had a valve sieze up and I took the tank to Walmart, gave them $15 + tax
or maybe less, was a couple years ago, and they gave me another tank, that
was full of propane. Did lose the 10# or so of propane in the bad tank.
