Does anyone know where PVC pipes thicker than 4.5" diameter (the thickest sold in Home Depot) can be purchased? Is there anything else that can be used instead?
I am currently building a small/medium-sized DRSSTC and I need a primary support that will block primary/secondary arcing.

You can always check with a plumbing supply house. There are a few local to me but you would need to find one in your area. I used to buy 12 inch pvc with a 1/2 inch wall to make speaker tubes out of back in the day. They sold me drop off pieces but you may need to buy a whole piece. Just get the phone book out

I think places here are just local places that only exist here. But we have a place called Godwin Plumbing, which is a master plumbing store around here. The largest they had was 6" diameter PVC pipe. Was like $35 for 3ft, not cheap if you ask me! But like said above, try local plumbing supply houses.

If you're not careful, a plastic tube can make flashovers worse. Inserting a thick piece of plastic between primary and secondary actually intensifies the electric field in the remaining air gap. So try to use thinnish plastic and leave a substantial clearance to the secondary.
I've used: Acrylic tube bought new (pretty expensive!) Offcuts of HDPE water main (either bought or scavenged from building sites as suggested above)
Other ideas: PVC air duct (used for lab fume hoods etc) Plastic sewer or drain pipe (the really big sizes are more likely to be available at a builder's merchant or farm supplies store, etc) Plastic trash can or laundry basket (try a mega furniture store like Ikea)
