What is the PSI coming from outlet?

I have a 2011 QBH Phateon and would like to fill my tires using the compressed air outlet located in the front compartment on the driver's side. I need to buy a 50ft hose to reach all the tires. I looked at a coiled hose at Home Depot but it stated along the side that it was rated for 200 PSI or less. Higher pressures could rupture it. So, trying to prevent problems I need to know what is the pressure of the air coming from that outlet. Any ideas? Any suggestions as to where to purchase a hose?

<150psi. It's the chassis air tank

A "coiled" as in self coiling 50ft will not fully "extend" to 50ft.

All you need is 50ft of 1/4in (I highly suggest Polyurethane) air hose (typically light blue colored and not cheap ~$30 from Lowes/HD) hose. It is extremely flexible and lightweight. 3/8 is overkill and non-polyurethane (i.e. PVC and rubber often red, orange, green) is stiffer/thicker/harder to store.

Air Pro 1/4 x 50' Polyurethane Air Hose

Also pick up the quick connect fitting while at Lowes/HD. There are several "types" and there is now a one fits all model (female end) sold by Lowes/HD.

Your outlet will be at the same pressure as the rest of your air system, 100-130 psi. Your dash gauges will tell you what there is. The box store hose is just fine for this use.

You'll want to get the proper air fittings for each end of the hose. There are several types which are each just a little different. Your coach may have come with an extra male end. Take it and match it up at the store.

You'll also want a tire filling adapter. Depending on your particular coach you may need one with an offset "foot" for filling valves on the rear tires. You can buy a gauge attached to the filling adapter or you can buy just the filling adapter and use whatever other gauge you normally use. Look at the tires and see what you'll need before you buy one.

When you fill your tires you'll need to have the engine running to keep building air supply and pressure. My rig will kick the compressor back on at a pressure higher than I run any of my tires so they fill without problems. Some folks report that their tire pressures are higher than the cut in pressure of the compressor so they need to pump the brakes to use air down to the cut in and then fill the tire while the compressor is filling the tanks. Your dash guages will tell you which method you'll need to use.

Best wishes with your new MH.

Began, save yourself a lot of trouble and wear & tear on your hands. Go to Sears and buy either their brand or the Porta Cable 6 gallon 150 lb air compressor to top off your tires. It will be so much easier and faster than using the onboard compressor.

I would suggest you buy y our hose at a truck stop.

What do I use: A portable pancake compressor from Sears, It says 150 PSI on the label and 160 on the pressure guage, which I've checked,, appears 160 is very close.

onboard air compressor for tire inflation

Thanks, everyone..
On my last MH I used a Sears compressor and it worked well. I just thought that using the onboard compressor would be faster and less noisy but now I'm not so sure.

VIAIR Corporation - 12 & 24 Volt Compressor Kits

Here are a couple light weight compact 12v air compressors. 12v high end air compressors work very nice, the don't take up valuable space and won't add unneeded weight.

Can be spendy though

Buyer beware. As is typical of most 12v compressors, they have duty cycles typically in the 10%-50% range. It is the exceedingly rare exception (and the provided link does have a couple) to find them with a 100% duty cycle.

To top off a 22.5 tire a 12v compressor will need to run for a long time and w/o a 100% duty cycle the compressor will self-destruct.

Duty cycle means how long can it run before allowing it cool. A 50% duty cycle means (and individual mfg specs on the time frame will vary) run for 5 mins and cool for 5++mins. You won't get very far with that kind of performance.

THis is the only brand I've seen with 100% duty cycle in a 12 volt air compressor. With my new to me class A I am set up tp use onboard air vs. a compressor.

A common air hose available at a home store, Walmart or Harbor freight will work just fine. I use 2 50'ers so I can get to the rear tires on the toad. To make it easy to store I put 4 pieces of aluminum flat bar (1"x1/8") bent into a "Z" shape on the inside of the left forward basement door. When inflating a tire, especially a 22.5, run the RPM up to high idle. Do this by turning on the cruise control and hitting the set button once. I've been using this technique for over 110,000 miles, the last 2 coaches, and don't have to deal with a separate compressor, or trying to untangle hoses.
