Thread: PVC for shop air lines

Tweet

I install air lines for body shops & industrial for a living.
PVC has NEVER been approved for air.
PVC is not approved for anything above ground. Even water.
The problem w/ PVC is it will shatter as it ages. Take a new piece of PVC & it bends very easily. Strike it with a hammer. In most cases, it will flex.
Now take a piece & either leave it in the sun or stick it in your 110 degree garage for a year. PVC has no UV protection & drys out above ground.
Then try to bend it. It will break & shatter. Hit it with a hammer. It will shatter like glass. Now picture those shards flying at you when that 80 psi line fails.
Urban myth? I've seen the results when PVC fails.
Copper or black steel is what we use.
