I was able to calc it down with a short piece of 3" CPVC pipe. Then
just use the CPVC x Grooved adapters. Hopefully this will fly. It is
all light hazard.

Do you mean the room is some kind of secure communications? I did one
recently- No metallic PENETRATION of the walls- (like an antenna) - I guess
a non metallic coupling would be like breaking the antenna- I went steel up
to the wall, steel to cpvc, cpvc through the wall, then back to steel. Is 4"
cpvc made?

Subject: NON-METALLIC COUPLING
I am working on a military project. I have to provide a non-metallic
coupling on one side of wall. It is a penetration into a secured area.
Any ideas on what to use as a non-metallic coupling for 4" sch 40 pipe?
