I plumbed the air in my shop using commercially available larger-diameter air hose(!), with appropriate NPT fittings.
Easy to install, meets code for air hoses, and is easily replaced, if needed. Strangely, the stock hose lengths fit the Shop perfectly.
The 3/4" diameter hoses provide all the CFM I have ever required.

The bursting danger is a real thing all seem to agree on. A shop I worked at had the air system plumbed in PVC, and of course, it failed. The most alarming part wasn't the shrapnel, as the air compressor was in a shack behind the building, and the failure occurred after hours. Shutting down the compressor wasn't done on a nightly basis, and after the outlet pipe blew apart, the compressor ran steady until morning when they found the burned remains of the fitting melting out of the comperssor's outlet fitting and a scorched mark on the wall...
