compressed air hardline

[meenaggie]

I have used schd 40 PVC in my garage with success. Small diameters (<1") are plenty for the flow and pressure rating of most all home use compressors (even larger 240V units). Some air compressor manufacturers recommend against this as they indicate the lubricants used in the compressor will degrade the PVC over time. I have a drier installed on the outlet to minimize oil and moisture carryover. I manage this by lubricating my tools every time I use them. I have carbon steel pipe at the quick connects and drops to give me something solid to anchor the lines to the wall with. PVC needs support every ~5 ft versus ~10+ with carbon steel. I have a flexible lead in line to isolate the PVC from the vibration of the compressor which also made it a lot easir to hook up. PM me if you want some pictures.

Disclaimer: The real concern is PVC is brittle and compressed air stores a lot of energy. If it does go it won't be good. Remember its primary use is for liquid which is not compressable.
