Big Boy Air Compressor Fittings?

Yes the fittings themselves are temporary, just enough to get the idea. So, keep it 3/4 then reduce it at the quick connect? And a ball valve between tank and regulator.

Yep, perfect. You’ll need a 3/4” street elbow and a 3/4” x 1//4” bushing and then you can attach the quick connect directly to the bushing.

you are going to get water out of that in the summer the reason people make long runs with pipe is so the water has time to condense ideally you need 35 feet of line 3/4 pipe sloping upwards so the water drains back towards the compresser

Depends on his location and how humid his summers are...
I'm in Ohio with a 80gl tank setup, I don't get water in the line, at least not for avg stuff, I don't do spray painting. Which changes the allowance of moisture in the air.

I run 3/4" pipe, with 3/8 quick connect and 1/2" air hose. The 3/8" QC is biggest you can get that has ranges of 1/4" to 1/2" NPT fittings.

All air has a certain amount of moisture in it, therefore the compressor will always make water. The water can’t be compressed and is heavier than air, so it will drop out. It has no where else to go other than to the bottom of the tank, hence the “drain daily” decals on every single reciprocating style compressor out there.

It is possible that you could see water downstream in the air lines, but this is usually under prolonged extremely heavy use when the air doesn’t have enough time to cool in the tank allowing the water to condense and drop out. In these instances the air is still hot enough that it will retain the water molecules as it’s being pushed towards the point of use. In cases like these an inline water knock-out, drip leg, desiccant or (preferably) refrigerated dryer is required.

Sloping piping upwards to allow water to drain backwards into the tank is simply absurd, and is counter intuitive to how compressed air piping is done.

Hence why traps are run in piping systems and when there is a tap, it is never pulled out of the bottom of a drop, always the side with a drip leg below it.

i forgot to add to use larger pipe i use 3/4 from the compressor to the down pipe where you have your water separator if the pipe is sloped down the whole way to the separator the condensed water will flow to the separator and overwhelm the water separator
