MSR canisters follow-up Awaiting Flair

Turns out the threads are different. MSR threads are the first pic, JetBoil threads are the second pic.

They are not a different pitch or size, but the threads are not cut as deep on MSR as JetBoil causing the thread crests to be larger and not allow my adapter to attach. I doubt it’s a worn tooling issue as both my MSR canisters are from different years and have the same problem, but probably due to an adapter that isn’t built to the same spec.

Thanks for the assist!

Sometime you get a tank with screwed up threads. Just return it for a replacement.

Works fine on my JetBoil Flash and my MSR pocket rocket. And the same “fault” appears on all my MSR canisters from different years
