The threads don't contribute to the seal like a tapered NPT pipe thread does. Just like on compressed gases, ie: propane, oxygen, argon, etc, the contact point is what makes the seal, not the threads. It's a compression type joint. Flared fittings are used a lot in petrochemical plants, particularly in instrumentation, where I work and Teflon is normally not used on the threads for this reason, it adds nothing to the joint integrity.
It is helpful however where the fitting threads into the can body, that is a tapered pipe fitting where the threads constitute the sealing surface.
