weldless fitting problems

[str8wire]

So I drilled my holes for a ball valve and a Bilchmann brewmometer. Everything leaks!!! What is the standard procedure for metal washers, silicone washers, etc...
Holes were drilled with a step bit to the correct size...not too big.
This is an old aluminum pot with thin side walls if that could make a difference.
I've tried every combination of washers and teflon tape, but still dripping.
How do you guys configure your:
1. Bilchmann Weldless Brewmometer
2. Ball valves????

Here's a great description of how to install a weldless valve.

I am about to do this very setup so I am very interested in your results.

How many O-rings are you using? Usually one on each side of the kettle does the trick.

Dunno. This kit from BargainFittings worked fine for me with one flat rubber washer on an aluminum kettle.

Honestly, I had issue too with my weldless fittings. My quick and easy solution...I just soldered them. See this thread: https://www.homebrewtalk.com/f51/soldering-stainless-steel-155782/

Really easy to do and you don't have to pay a welder. Just make sure all components (including your kettle) are SS. Aluminum requires a different flux and/or solder.

Thats was my initial plan. Thats how I did it with my MLT and BK...both work fine, but not with my aluminum pot. I really think that the washers I am using are to thin to make the seal with the curvature of the pot and the flat metal washer.
