Where is the male quick coupler for putting air into coach.
You have to supply your own. They didn't come from the factory with the plan to add air, just to use the onboard air. If you are talking about where the air comes out then usually on passenger side first compartment back from front.
I just made a male to male adapter, with a valve on it. Make sure you have a good drier on your compressor.
Some have Tee'd in at the drier at the rear, so it runs through the coach drier.

Thanks, now I can quit looking. I will install my own or maybe I can hook 2 male ends together and put air into the system from
the female quick coupler. Putting in before the air dryer is a great idea
This may or may not work on your coach.
On older models (like mine) the "tire filler" air connection comes directly off the wet tank, with no check valves to prevent "reverse flow". I can use the double male connector plugged into my air hose and air up my whole coach using a portable air compressor.
On newer coaches, the source of the tire filler hose is usually
not directly off the wet tank, but comes from somewhere else in the air system. On these coaches, you cannot pressure up the whole coach air system using the double male connector on the tire hose.
Easy to find out how your coach works - just hook up a portable compressor to the tire filler hose and see what happens. If your dash air gauges show a increase in pressure then you're good to go. If not, you will need to tap into the air system at some other point.
OR, look at your air system diagram and see if it shows the source of the air going to the tire filler connection.
And yes, it is a good idea to have a water filter on the portable compressor if
regularly used to air up the coach. But trying it out one time without a water filter won't cause any harm. IMHO
I can fill the tanks using the two male couplers, but I put in a Tee in front of the dyer. Thanks for the idea Chris
Here's what I use.

Where did you get that, John? I could use something like that for my outboard aux. compressor. ^.^d
Put a female disconnect in the coach Compressor to Air Dryer line?
The coach compressor? The tire fill hose has already gone through the dryer.
Craneman, I think he is talking about putting air into coach through tire hose from a portable compressor that has no dryer
But I may be wrong!!!

In the air line, between the coach compressor and the coach air dryer, install the apporpriate plumbing to charge the coach air system from an alternate source.

I added this connection this summer to my 2001 U320. This will charge the wet and front and rear service tanks and pressurize the leveling system. It does not add air to the HWH tank. Assuming all of your check valves and pressure protection valves are functional. Air added this way goes through the coach air dryer.

Coaches from different years and different models may be different. Find the air schematic for your coach. Make sure you understand how it works before you start making modifications. Use DOT approved fittings when connecting nylon air lines. Use PTFE pipe sealant, not tape on threaded connections.
I put a tee in at the air dryer and then a valve and then a male quick coupler and when I'm not using it I will take the quick coupler
off and put a plug in the valve. That whey I know it's safe. The female coupler on mine is in with the propane tank.
