I am trying to create MLT from 10 gallon rubbermaid cooler. I cannot completely fasten the female brass adapter (Watts A-298) to the 3/8'' MIP brass nipple (Watts A-786)
I have a gap between these two. It looks similar to the FlyGuy's picture:
But on one of the last pictures he does not seem to have this gap anymore when he added external parts
How to screw this so I do not have that gap between A-298 and SS washer?
I assume that I do not just pull the whole thing outside because the flat part of Watts A-786 will be out of the cooler and I would be unable to secure it in place.
