Ryan, I’ve been mounting the nozzles another way that is easy to change out quickly.
I’m working on a no-weld solution (like others around here 
), and I’m using a large surface area flange (1 1/2 inch) with one inch Kaowool blanket gasket. The Kaowool is fragile and needs lots of area to avoid fretting and subsequent breakdown. The rock wool collapses as you clamp it down, and squeezes the bolts so that you don’t have air leaks there
(best to use bolts with smooth shanks).
So far, so good.
It is very quick and easy to change out whatever is mounted this way. Usually you can reuse the gasket without trouble.
