This is really a continuation of my IR compressor rebuild (IR Air Compressor Rebuild) but I thought for searching reasons, a new thread would be helpful.
After I got the compressor in place I looked at many different options/opinions for air piping in my shop (Black Iron, Copper, PVC, Aluminum, etc.)
-PVC was a no go right away, it degrades and ultimately will fail at the joints or even worse explode.
-Aluminum would be nice but is expensive and time consuming threading all the joints. I have a rigid pipe threader and would rather fight snakes than operate it.
-Copper is REALLY EXPENSIVE and I can't solder to save my life.
-Black iron pipe will rust inside and ultimately end up blowing rust debris into my air tools. Plus the whole threading thing.
-Max Line is expensive but really easy to install. 200psi working pressure and won't corrode.
I purchased the Max Line 3/4" Master kit at Northern Tool for 167$. Plus an additional 150$ worth of additional fittings that I would need in addition to the Master kit. I had already had a Norgren FLR so that was a big plus.
The Max Line is HDPE/Aluminum/HDPE. It holds it shape really well with the aluminum core, so bending in the corners was easy. After cutting you use a chamfer tool to prep the end for the connectors and push the line into the connectors and tighten a locking collar to hold everything nice and tight. Quality is top notch. All stainless connectors/couplings and solid aluminum distribution blocks with drain. I had 4 stations and FLR installed in 3 hrs time. I'm still lacking a couple of air line connections for the air reels but overall I'm really pleased with the results.
