What do you do to keep them from backing off during rapid or full auto fire?

Depends on the can/caliber, but teflon tape, a thin o-ring or, a small amount of blue loctite will help. Although it's still a good idea to check it after every mag.

I use the blue locktite but also use a industrial sling pipe wrench to tighten it down cold so it is more than finger tight. It doesn't back off as has been demonstrated to me in multiple classes shooting multiple hundred rounds per class. Check out your system well though so you can prove it to yourself.

Just tighten it down hard, and check it after a few mags of shooting.

Wouldn't be my choice. Teflon reduces friction on the threads (not increases it). Teflon also cold flows at temperature and can sublimate at elevated temps. It works well as a liquid or vapor sealant but that isn't really very important in a suppressor.

The wrench is the best way to go. The Teflon helps by taking up the space between the threads so that there is little to no vibration and thus less chance of loosening, but teflon melts at 620F, so at that point it will cease to work in that regard. This is the major problem with thread sealants- they are mostly polymer materials with low to medium temperature melting points. The high temp thread sealants are glass fiber based, and they have much lower torque ratings to the extent that they are not as optimal as the polymer thread sealants which have the lower temperature threshold limitations.
