Compressor Fittings Questions...

[Ole Anderson]

If the fittings on the hose aren't high flow, then doesn't that defeat the purpose of high flow couplers and plugs?

Quick answer: Not necessarily, most of your friction loss will be in the hose itself.

Think of your garden hose. You have a 60' hose 5/8" ID and you have a sprayer at the end with a 1/4" orifice. It works.

My couplers have the hose barb built into them, but I didn't pay anything like this much for any one.

Derek,
Here is some information from another of your threads (see link below). I'm not sure if my hose connectors are "high flow" or not. I have mostly SpeedAire style connectors purchased from Grainger many years ago. In any case, I use 3/8" air hose that does have the 1/4" NPT ends installed. Although the hole may look small, this setup has been sufficient for all my work. My compressor is 7.5 HP rated at 24 cfm. I run glass beaders (sand blaster), spray guns, air tools, cnc tool changers, etc. with no problems due to lack of air supply. Do you have a specific application that will demand very high cfm over and above those I have listed? I am just curious, because I don't think I ever remember seeing a discussion about "high flow" vs "regular flow" air couplers before.

David, the high flow connectors have a much larger ID than conventional connectors. For me, that means I can run 1/4 connectors on 3/8 hose and still maintain close to 3/8 all the way thru. I'd like to just go 3/8 or even 1/2, however that would mean swapping out all of my connectors on all of my tools.
I'll be doing some sand blasting and using some impact wrenches, along with various nailers, which don't require as much CFM to operate. I'm upgrading my compressor, so I figured I may as well upgrade what hose and connectors that I can.
