I have reworked my keggle (converted sanke keg used as a kettle) to be all stainless steel 1/2″ NPT fittings. At the same time I have added camlock fittings to allow quick and easy disconnects to be used. This doesnt help much today but it will be very important when I begin using my pump, plate chiller, and hop rocket.
Pictured from left to right: 1/2″ Street 90 (threads milled smooth), 1/2″ camlock B-type, 1/2″ camlock F-type, 1/2″ ballvalve, close nipple, welded 1/2″ NPT coupler.
I will post more information later on why i chose camlocks and how I use them in my brewery.
Always use teflon tape (polytetrafluoroethylene = PTFE ) when joining treaded fittings together. Always wrap the threads clockwise and when you are using stainless fittings give it a few extra wraps (i try to get about 4-5 wraps). Do not over tighten your fittings, I did not know this the last time I installed my keggle ball valve and it was very difficult to remove. A prefect tightness is some where between finger tight and needing a wrench.
