I am having issues wit hthe plastic fittings in my titanium shell/tube exchanger. When the system is working properly, it seems ok as the water in the plastic side is cool, but when something goes wrong, like my 3-way valve leaking, it gets very hot leaks. I was thinking perhaps I would be better with a metal-metal seal there. Not surewhat is out there in 1 1/2" from metal and how to get back to plastic. Do they even make a male adapter with a plastic transition? Or could I use some kind of metal union, still need a plastic transition though.

Still grasping at how to get from the flange to PVC. Could I use this?
1 1/2" Male Adapter Mipt x Slip CPVC Fitting Schedule 80
Seems the CPVC should be fine with the temps and then I could glue standard PVC into it. Would you think the threads would leak? I am assuming the white PVC is just not rated to handle that temp and it is deforming, but a glue joint should be fine. I have had no issue with the joins up or downstream that are all glued.
Any reason I would need sch 80 vs sch 40? I only have about 20psi in the system.
