I have made homemade no-weld spigots for repurposed Sanke kegs using copper threaded adapters and teflon tape. Actually worked with a little trial and error. The stuff is really handy for that kind of project.
For stuff like gas fittings I still use old fashion pipe dope.
I must admit, this is a bit disappointingā¦ I have tried like 5 times and no luck getting it to seal. I have tried twice more this morning with no luck. I must be doing something wrong but have not figured it outā¦ I was all excited to start my first brew batch today but looks like I will be delayedā¦ Keep your fingers crossed folks!
If the gaskets (washers, seals, whatever) are beveled silicone the bevel probably goes against the glass. I would wet them and assemble everything. Donāt strong arm it. Just go hand tight then let it sit for awhile until it is dry. Last step is to cross your fingers and if it seals be gentle with it.
I have a plastic bucket that I added a spigot to and after a couple of batches that clogged the spigot/tubing went back to a racking cane. Sounded like a good idea.
