Tightening fittings.. 2 tight?

How tight do you usually tighen your fittings into your tank and so forth? 

a common rule for pipe fittings is to leave 3 threads showing. some people also go 1.5 turns past hand tight which is usually enough when you use teflon or nickle antiseize tape.

thats a damn good question you just asked..........

Wow man that is a hard one to answer. I have been doing this stuff for so long I just have a feel for it now but that doesn't help you much. I searched google and couldn't find anything, strange. One important thing I learned is that if you like to use teflon tape you should know its not meant to be used as a sealant, it's intended to be a lube, shocked me to learn that one but it did explain why I broke fittings when I would use tape.  I think a safe bet is to go as tight as you can by hand plus 1 1/2 to 2 turns.

It will cause you to stretch threads, break fittings, and whatever else. I suggest using loctite 545 liquid thread sealer, it seals threads nicely and does not  lock them. that plus 1.5 to 2 turns past hand tight and you should be good to go

I always use teflon or nickle on stainless stuff just cause you may have to take it back out one day. never used any liquid sealer but they make it so im sure it works. 90s are the only time you may have to come close to overtightening to point them the right direction.
