Element gasket

I'm getting ready to build an electric boiler, but I was wondering what everyone is using for a gasket, other than the rubber one that the element comes with?

Depends on what mount you are using? Many use a NPT mount instead of a nps. So PTFE tape is used on the threads. And it won't screw in all the way to need a gasket.

I already bought a 1" stainless lock nut with straight threads. It's a very thin gauge stainless stock pot, so I was hoping to go weldless. I was planning on punching a hole in the boiler, putting the nut on the inside, and threading the element into it. I neglected to think that I'd need some type of replacement gasket between the element and the outside of the boiler.

It would probably be best to have one on both sides. Can make a gasket wrapped in PTFE tape for the inside. And wrap the gasket that came with it. In PTFE.

I am planning to use a PTFE o-ring. The element will screw into a 2" ferrule NPT adapter.

If you are using a NPT adapter. You shouldn't need the o-ring. PTFE tape on the threads should be enough.

I just figured I would replace the rubber or silicone o ring with a PTFE one. That tape sure would be cheaper and easier though. Will that seal it well enough?

if you wrap the tape around enough just keep going over the same spot when you tighten it against the side it will squish down forming a seal

Thanks everyone! I'll try wrapping the stock gasket with teflon tape, and if that doesn't work, I'll buy one of the teflon o-rings.
