I tightened one of my termovar flange nuts too tight and it broke. Is there any reason why I can't remove the flange completely and attach directly to the 1 1/2" threads on the termovar with a 1 1/2" female black steel fitting?
Those nuts are pretty cheap looking,I used the gaskets plus a coating of high temp RTV.no leaks now,I didn't dare tighten them too much.I don't know if the theads are the same or not.they need to have a taper in order to seal.If you install a union,you could always try it and see,that way if it doesn't seal you only have to open the union.Just a thought.
