Thread sealant is used to seal the threads in a tapered pipe fitting. A tapered pipe fitting is not designed to seal without it, and its only pure luck if you manage to get a seal out of a tapered pipe thread without sealant.

Thread sealant has no business on the threads of a AN flare nut. The 37 degree flare seat is what provides the seal. With the flare correctly seated, it will be sealed. There is nothing for the threads to seal as the fluid would never make it that far. AN straight threads should not have any thread sealant on them, ever.

Thread tape could never interfere with the swivel, as the swivel is on the opposite end of the hose end, closer to the hose, not near the flare. However, you should have no thread tape on anything that isnt a tapered pipe thread anyway, so its a moot point.
