Ok so I'm getting an education on the difference between NPT and NPS threads.
I've got my 15 gallon pot.
I've got a 5500 watt heater element.
I need a female fitting that allows the element to screw down far enough to compress the neoprene gasket. The only thing I have locally is a 1-inch galvanized coupling. All the copper and SS fittings I have are NPT or tapered.
I can't get in touch with either of my rental stores to see if they have a tap that I could use to open up a stainless steel fitting I have laying around.
Any thoughts or ideas? Is a galvanized fitting OK?
I plan to just drill into the pot with a 1.5 inch hole saw and grind away whatever I need to fit.
