Interesting how the smaller propane jar leaks. I found out the other day my propane jar for the torch wouldn't close properly and hiss a bit, so I had to reinstall the torch head repeatedly until it doesn't hiss. I thought it was just that one but looks like it's more common than I thought. The butane can for either refill lighter or stove never leaks thou.

Going to be very cautious about this from now on.
