I made my own bottle fill set up and it has worked well for the past year. I am filling a couple bottles today and I feel a leak around my hand by the quarter turn valve and gauge. I get some snoop and spray it around to find most of the threaded fittings are leaking. I used ARP thread sealer when I assembled them. Does the NOS attack thread sealer? Do I need a special thread sealer? My buddy told me to use red loctite since I won't be taking anything apart. Thoughts????
