A recent Residence Hall contruction at the University where I work ended up with a "pile" of Pex tubing cut-offs. Some quite long (50 feet?). This and the many debates over copper vs iron vs PVC has me wondering about the practicality or pros and cons to using Pex to plumb Compressed air in a shop. So three questions come to mind;
1) Any one out there done this?
2) In relation to other materials how expensive would Pex be? I have the pipe for nothing and access to the $300 tool so that's not an issue for me. The cost of the fitting and the ease of attaching hose fittings comes to mind.
3) What are the pros and cons of the physical application? The pipe itself is certainly cheaper than copper. It wouldn't be as puncture proof as iron but the perception of the likelyhood of it shattering under pressure that seems to be the worry with PVC doesn't seem to be there. etc.
Thanks in advance,
