So my new regulator arrived today and being no stranger or noob to plumbing air compressor lines, I did the usual wrapping of Tef tape on all of the fittings before screwing them in. I had to use a brass right angle adapter from the tank outlet to the regulator so I used a little extra Tef tape on each connection. I see that I have leaks from every joint of that setup. And the pressure gauge that came with the regulator if screwed in tight not only leaks but faces downward where it cannot be seen. What do I need to use to fix this when certain connections require that they be in a certain position? Thanks.
