I was swapping tanks and may have over tightened the nut. It is no longer flat where the nylon washer goes and won't seal anymore at all. I attached two pictures to show. Is there a way I can fix this?
I replaced the nylon washer and it seems to be not leaking now so maybe I didn't break it after all. I am a little untrusting of this regulator now. What brand is recommended? I don't want to spend a fortune and I don't know that I need the second gauge since it resides in the fridge and the second gauge doesn't read when cold.
