That was just a guess, but the sides are thicker than the plastic on the screw cap. Doesn't matter how thick it is once you chamfer the inside it's thin enough to screw the flange together.

Thanks JR

Did you have to use any sealant/silicone etc with the two piece flange?

I put sealant on the outside of the tank where the threads came through, then ptfe'd the thread and screwed the outer on tight. The ptfe'd the thread on the element and screwed in to the flange. ( that sounds wrong)

Interesting looking setup there JR, I may well have to copy this if my existing (untested) setup leaks..

Could you clarify what you meant by "It is in 2 half's and inside the tank is a ring bigger than the thread", scuse me for being a bit dim but my brain can't see how it tightens...

The back ring that goes into the tank is fully threaded, so the outside part screws up
