The duct tape is the last line fo defense so to speak. I couldn't find anything that would connect PVC to Vinyl and still be flexable. There is about a 3/32 gap between the PVC and vinyl. So I made a compression fitting so the vinyl is forced ******d into the PVC. That should be enough but for added measure I put some silcone caulk in the rest of the gap. The duct tape is the last line of defense and also to hide the white caulk.
I really need to find a way to tap NPT fittings. I haven't been able to find a local store that sells them.
I normally run pos pressure to avoid dust bunnys. My theoretical reason is increased pressure normally means higher density so higher density air means better cooling.
