Bill,
I could be all wrong because I am just basing my comments on an enlargement of a low res picture. If you look carefully at the pic Russ posted there appears to be a step change in diameter instead of a taper you would expect on that thread. I surmise the threads simply sheared from the main body of the fitting. The metal that sheared off remained in the female thread of the canister. If that is what happened, then time, vibration, and corrosion all contribute to metal fatigue. Again, all of that rigaramole is conjecture based on the picture. The threads shearing off explains why the new part wouldn't thread in.
