Air lines and NPT fittings.
by Zack A
I have a brand new 33 gallon Husky air compressor and want my tools to get the most out of it.
When I bought it I made the mistake of picking up the first 25' 3/8" rubber hose I saw. When I got home I and opened it up I realized that the 3/8" hose had 1/4" NPT fittings. I was pretty annoyed to discover the quick connect set I purchased also had 1/4" fittings.
I understand that pretty much all air tools have 1/4" fittings, but I wanted to maximize flow.
I immediately went online and purchased a 25' 1/2" rubber hose with 1/2" fittings, a couple 1/2" NPT quick couplers, the 1/2" plugs for the quick connects, and about $30 worth of 1/4" male x 1/2" male fittings that would allow me to use 1/2" plugs on the 1/4" tool inlets.
Lastly, I also replaced the standard 1/4" quick connect on the compressor with a 1/2" one. To be honest, I didn't noticed much of a performance difference, the tools just got louder.
My question is, did I just waste about $100? Was the 25' 3/8" hose with 1/4" fittings already large enough to prevent pressure drop?
My impact gun uses 5 cfm at 90 psi, and my compressor supposedly puts out 5.1 cfm at 90 psi. Just looking for some opinions. Any help appreciated!
