Yep...FAIL. Leaks like there's no tomorrow. I'll try again later....but I think I need better flux first. I just hate to pay as much as the local welding supply shop wants for the Harris.

You need to get and use Harris Stay-Clean Liquid flux. I've not found anything else that works very well with SS. It's more important than the solder you choose. Plus, the flux is not so expensive to get. Solder? Yea...

Go to airgas and buy their brand liquid flux and solder. It's less than $10 and will last for a good 10 couplings.

I have been following this thread for awhile but I have yet to come across any posting of what size people are using to pull Couplings and half coupling thru the keg walls.
What I am looking for are Concentric reducers to stretch the hole out for the couplings.
The sizes I need them for are 1/2" couplings and 1" half coupling for electric elements.
What is the rule of thumb. Next size down from what you are wanting to pull thru?
I found some on grainger, but not sure what size I should get. They are not cheap being stainless.
Thanks

This part is nice because you can use the other end for making dimples for 1/2" NPT fittings.

Make a 1-5/16" hole.

I was never able to find the Harris flux but here is an option from Grainger that worked very well for me.
