Does anyone know of any companies that sell kettles with 1 inch NPT fittings in them already. After failing to silver solder a welding spud into my keggle and paying a welder way too much to do it for me, I was wondering if there were any pre made ones commercially available. I would like to brew 15 gallons at a time so I am looking for a 20-22 gallon kettle. The only ones that I have been able to find are from Stout tanks. They look amazing, but I was looking for options before pulling the trigger.
