Before I leave this subject of Dust Collection, I need another best
suggestion. What is the best way to connect standard 4 inch flex hose
to PVC piped DC system?

I use aluminum blast gates, which are slightly smaller than the 4" PVC
Pipe, I glue the blast gate into the pipe with silicone sealant. On
the flex hose size I use a pipe clamp.
