Has anyone any ideas about a suitable thread sealant to make an M8
thread on a boron-nitride tube gas tight in a stainless steel block (to
roughly 10" of water), whilst the stainless is cooking at at least 400
Centigrade ? I am at a complete loss ! I have tried Zypcoat boron
nitride paint, but once the carrier has dispersed, the thing still
leaks.

Thanks

Steve
