Anybody had a disposable propane bottle leak on them? Picked up a couple of the tall skinny ones from my wife's late uncle, unknown how old they are but they appeared to be unused. After I partially used one on the camp stove, I could hear it hissing. Tried poking the valve a couple times, but it was still going. Found out I could buy some brass caps to cap them off, so I ordered a few. Put my torch head on in the meantime to hold it until they arrive, but that's a first for me.
