And here it is, there's a miniscule leak on the outside, but it might have just been condensation. Either way I'll probably take it apart again and add a gasket to the outside.
Thanks for the feedback guys. It's a 2 inch nipple, I couldnt find a 1 1/2, but it looks like a one inch will work as well. Also, it's a 5 gallon igloo round cooler. And my valve is a 3 pc. I tried threading the other side, but same deal, about 3 turns.
Hello,
So I ordered a bunch of stainless steel fittings and ball valve for my mash tun and when I went to attach the ball valve to the nipple, low and behold it only turned about three times. I'm still left with around an inch of space and I can't get a seal because I can not tighten it...
