Hello all, I am a big fan of the website and have used it many times when I had problems. This is my first post however, and I am building my own mash tun to try and save some money. I have run into some trouble though because it keeps on leaking on me. I can't seem to get the ball valve, brass nipple, cooler seal, and the female barb adapter to stay tightly sealed.
I used this video to help:
I am using:
3/8" ball valve
3/8" male adapter and 3/8" female adapter
four 5/8" washers (I don't thnk they are fender washers, not really that thick)
5/8" O rings
3/8" - 1 1/2" brass nipple
the seal from my cooler
I have the braided stainless seal supply hose clamped up as well
The cooler keeps leaking from the outside of the hole, like it is not tight in the rubber seal from the cooler. THe ball valve is loose when I touch it, so that is why it leaks, but I have both sides as tight on the threads as possible and it is still not tight. Any suggestions? Is my brass nipple too long, or possibly do I need more washers?
