Default weld-on heating element flange

I'm building a HLT with an electric element, have been trying to find a stainless flange in 1" NPS to have welded on, but my searches have come up with nothing. Anyone know where I could acquire such a thing?

would that work? I was thinking that with the curve of the keg a plain nut would have too much gap to TIG on

There are 1" couplers at bargain fittings. I have them welded in my kegs. They're pipe vs straight threaded, but the element still threads in and seals. If I were to do it again though, I'd have the standard lock nuts welded on. They can be welded or silver soldered.

Would you go to the locknut because the fitting is NPT and not NPS? or some other reason?

You might consider this. Look under "weld on tank fittings"

Because of the threads and the compactness. You could always just cut the coupler to whatever length you needed, but why do all that when you get the correct threads at the desired thickness already? I was not aware you could weld the nuts to a keg at the time. That's why I did the coupler. I was also told that the coupler was the same threads. It wasn't until after the welding that I learned they were not.

The 1" SS version is $30.
This is $9
This (what I bought) is $4.75 He added the note at the bottom based on my emailed response. I was teh first to buy this after being the one to request he sell it. I still speak nothing but great things about Bargainfittings. He offered to refund me, but I already welded them in and they worked after teflon tape so..

Both SS.

You should be able to weld a 1" locknut on no problem at all.

Thanks for all the input guys, I think I'll just go the way of the locknut, tell my welder to suck it up, and bring him a sixer when I drop it off
