Can anyone steer me to the proper quick connect adapter to hook up to the front air port under the hood of my Spartan chassis?
I want to hook up an air line for tires, etc. and don't know which adapter I need. A part number, link or anything would be helpful.

Hello, The best thing I can tell you to do is take the quick coupler(female end) off the end of the hose in the front of your coach and take it to the hardware store and find the proper air hose fitting that fits it.

These air fittings are pretty much standard.
Take a picture of it, with a ruler next to it and go to your local auto parts place.
Shouldn't take tem more than 2 minutes to get you the right one.

They look standard from the outside. They are very different with the location of the grooves and ribs that lock them in place. If you look for the ones that have a wide flat rib (maybe 1/4') that is the one that fits. I have used air tools all my life and the one Newmar uses is not as common as most used around here (Indiana). It is still available at most auto parts stores.

Look for them at Amazon.com. They are listed as 1/4" male automotive plug MP3238. The 1/4" is thread size, yours may be different but you can see the shape of the part that engages female coupler.
At least this is what my last two Newmars on Spartan required.

Thanks a bunch for your help Dave. I'll try one of those. The picture on Amazon will probably help me find one locally. If not, I'll order one from them.

Any hardware or most auto parts carry them even Walmart.

Nope, I looked to see if there was one there. I'd heard there's usually one attached to let the tow truck driver know which one he'll need in case of towing the coach.
I did find one that works and I'm now in business!
Thanks for everyone's input.

Buy fittings that conform to the "Industrial Interchange" standards and you can't fail. These fittings are made to accept any of the different types of fittings, ie: they are universal.

There are several different standards and styles of quick-disconnect air couplers; the one that turned out to be on mine is the "automotive" style as currently sold at Lowes: Shop Kobalt 1/4-in Steel Female Automotive Plug at Lowes.com

This is not to be confused with the much-more-common "industrial" style, which is what one commonly finds on air tools: Shop Kobalt 1/4-in Steel Industrial Plug (M) at Lowes.com

And, I did find a mating plug tied to my coupler air line. Over the years it had turned into a ball of rust and was unusable.

Um, be careful when using that to air up tires. You could easily let air OUT of your tires if your air tanks fall below the pounds in your tire and your compressor doesn't kick on. You have to sort of have someone watch the air guage while you're airing the tires. Don't ask me how I know this.

Muddypaws · 08-13-2013, 10:03 AM

My tires require 115psi in front and 100 in the rear. The onboard compressor would never deliver more than 80 no matter what I tried. High idle, pumping the air brake, whatever. Some will say they've been successful, I wasn't.

I find it a lot easier to use a 'Husky' 150psi portable I got from Home Depot for about $100. It's noisy as all get out, but still quieter than firing up the CAT. It get up to 150 in about 60 seconds.

akeyzoo · 08-13-2013, 10:44 AM

I am with muddypaws though I haven't purchased yet.

At first I thought I may use that plug for inflatable toys for the kids and tires in an emergency. I quickly realized there is nearly NO usable stored air pressure after a short period and firing up my C9 to inflate the pool toys seems ridiculous. Add to that the fact that my hydraulic leveling system doesnt much like having the air bags inflated while they are deployed and I quickly realized this was not a good solution.

Oh, and my fronts run @120psi...
