Ever taken a good look at the threads on a canister?

Notice how they don’t sharpen down to a “point” the way most threads do. These threads don’t give your stove a lot to grip on to. Use them wrong, and you’ll wear out your stove (literally).

I’ve assembled some basic tips for taking care of your stove’s threads in Canister Stoves 101: Thread Care

But, I had this Exponent F1 Ultralight that developed an obnoxious characteristic

When I didn't tighten it very tight, it would be okay in the evening, but overnight when it got colder, something shrank a little and it started leaking gas. In the morning it was empty.

Maybe that was just one stove. I got a new one (Pocket Rocket) which doesn't seem to have that problem.

Now, I'm paranoid and I over-tighten my stove.

I suppose I could unscrew stove over night.

That’s weird. I haven’t heard of that happening. I suspect the “O” ring inside probably shrank in the cold.

I suppose I could unscrew stove over night.

That sounds like the way to go.

It is worth mentioning that stoves with aluminium threads are more prone to wearing out than stoves with brass threads, as aluminium is softer than brass.
The MSR Pocket Rocket is a particular example.
Reports here and here.

MOST annoying. Bad design of the canister.

The Camping Gaz design is probably the best I’ve seen in terms of durability. Coleman Max/PowerMax is also nice in that there are no threads to wear out, but I’ve seen the “fingers” break and the interior of the rotating cam is subject to stripping.
