As a side note/question-which quick connects do you guys use.Short or long style??.

Gary,
Ask your plumber friend what they run in new houses for their gas line to the furnace or fireplace logs. The rating on A53 pipe is "WOG" which is Water, Oil and Gas, and air is a Gas. Also looking at Lowes, since you mention them, look at their on-line information on black pipe and you will see that they say it is hydrostatically tested to 150 psig.

1/2" x 10' Black Iron Pipe
• Hydrostatic Tested
• 150 psi
• Do not use with drinking water
• Pressure tested and protected from corrosion with varnish

As you look at the costs of materials don't omit the fittings in your calculation, and consider that threading cut ends of the black pipe takes time and tools. Sweating a 1/2" copper fitting is pretty fast, and the elbows and tees are pretty cheap in the contractor packs. If you do choose to use black pipe look at getting it in 20' sections vs the 10'ers sold at the box stores. Less connections on those long runs.

I switched over to the DeVilbiss 3/8" ID QC's that have the auto retracting collar - nice to be able to push it onto a tool with one hand vs having to pull the collar back, push the tool in, and ensure that the collar is back up solid. Hose Fittings

Roger, did you have a local supplier for these DeVilbiss QC's or did you have to go online?

Mike,
My local independent paint shop turned me on to them, first because they have a larger, 3/8" port for less restriction, but then for the ease of use when plugging a paint gun on the hose. My other old male QC fittings (non DeVilbiss) fit, but they leak a bit static. The fix is to replace all the male fittings, just live with a bit of "SSSSS" when they're laying around, or unhook them. The paint guns with the mating fittings are tight, no leaking.
