    Yes, you do not want to apply heat anywhere else, otherwise the reg is toast.
    It's a pinpoint thing, otherwise, retap it. IDK, seems like a huge PITA.

    So you are in already this far, may as well retap.

    I ended up re-tapping a little without any fluid. Cleared a little out but at the cost of a little more thread damage. The CGA inlet screws in all the way it is supposed to and is tight, so I just went ahead and assembled one through the solenoid. A leak test is in process now, but no obvious leaks. I used 4 turns of Blue Monster teflon tape on all threads.

    Sounds like progress. Will you be assembling both regulators or just one?

    Victor tosses stainless regs with stripped thread. They do not repair them.
    That is part of the problem with stainless bodies. The threads are brittle and if you do not use Teflon tape, the threads can be damaged. The only way to know if the unit is safe is to try it. Be careful if you decide to.

    I have had one set up for a few days now with about 1100 psi from the tank. No leaks or issues so far. The inlet screwed in all the way it was supposed to and feels firm and secure.

    Victor used no teflon tape on the factory installed CGA 350 fitting except for a couple of threads where the CGA inlet met the regulator exterior. The interior threads had no protection.

    I put 4 turns of Blue Monster teflon tape on all threads.

    I do wish I had not let the auto shop use the air tool to remove the CGA 350 fittings. I have no way of knowing if my problem would not have occurred if they had been removed more carefully.

    BTW, the correct size for the CGA fitting hex is 11/16". I found 18mm too big and 17mm maddeningly just barely too small.

    Yeah, I save the air tools for brass regulators and fittings. Hand tools for stainless. ;)
    It's all a learning experience. As long as you don't have leaks and the unit fitting is tight, you'll be okay.
