Teflon tape isnt a good choice, for all the above reasons. BUT, NPT sealer with teflon ( the paste) works well. When you are doing your mock up assembly, mark the cylinders where your AN822-4D's should point (sharpie). Seal the fitting, ans after hand snug, you should be able to get them to tighten up and index to the mark. Be careful on aluminum to aluminum, and really cranking on them---yep you CAN break a fitting, or strip the cylinder.

Ive been using this teflon paste for years in alot higher pressure applications than RV brake systems with no issues. Its all in the preparation.
