Q: What size MORRFlate do I need to fit my vehicle?

A: The easiest way to tell is to measure your wheelbase. A wheelbase is the measurement from the center of your front wheel hub, to the center of your rear wheel hub. If your wheelbase is 125 inches (317cm) or less, then the regular Quad will work. If your wheelbase is 155 inches (394cm) or less, then the Quad+ will work for you. If you need something longer, then contact us for a custom kit.

If you are considering a 2 tire kit, then you will want to think about which 2 tires you want to air up at a time. If you want to do one side of your vehicle, and then the other side, the regular Duo should work. If you want to do the front tires, and then the back tires, you will want the Duo+.

Q: Do I need a minimum volume output compressor to make the MORRFlate work?

A: Nope, no minimum! However, there is a maximum on it: Roughly 20-25 CFM. This is limited by the valve stems on your tires. So, if you have high flow valve stems, this number can be increased drastically. Have you ever used a compressor, where, while airing up, the gauge was reading a higher PSI than when the compressor was off? This indicates that your compressor puts out more air than your inflation system can handle. In other words, there is a bottleneck in the system (usually your tire valve stems), and the compressor is putting out more air than the bottleneck can handle.

This usually happens around 2.5 CFM and higher being pushed into a single tire. This is generally bad on a compressor because the back log of air pressure in the compressor makes the compressor work harder, run hotter, and use more power from your battery. By splitting the airflow 4 ways, you alleviate the back log of pressure on the compressor. This helps your $500 ARB Twin Compressor run cooler, and last much longer.

Q: Is my compressor powerful enough to push air into all 4 tires at once?

A: Absolutely!  If you were able to fill up your tires before, then using a MORRFlate Multi Tire Inflation Deflation™ Kit will just be easier on your compressor. Just make sure that your compressor is rated for the PSI that you plan on putting in your tires.

Q: How long does it take to fill up a set of 4 tires with the MORRFlate?

A: Your mileage may vary. With a Smittybilt 2781 (5.65CFM) compressor, we were able to fill up our set of 37×12.50×15 tires in under 14 minutes. This was from the time we connected the MORRFlate Quad 4 Tire Inflation Deflation™ Kit to the tires, to the time we turned off the compressor. We fill up our 28 inch Rav4 tires in under 5 minutes.

With a new ARB Twin Air Compressor and 5 gallon air tank on board air setup, it takes us on average of 5 minutes on the dot to air up a set of four 36×13.50×15 Iroks from 5psi to 30psi.

We have personally aired up some 33×12.50×17 tires with a PowerTank in under 45 seconds. And 39.50×13.50×17 Iroks with an ARB Twin Air Compressor and no air tank in under 12 minutes. If you add an air tank into the mix, you will get even faster times.

Deflating our 37×12.50×15 tires was even quicker at 11 minutes, 9 seconds. Our tires are also mounted on a 3500lb 1st Gen 4Runner. So, your 5,000lb Jeep or 7,000lb full size will air down even quicker with more weight pushing the air out of the tires.

Q: What air connection is on the manifold to connect to an air source?

A: The ball valve has an “Industrial/Milton Adapter” to connect into an air source. You will need an “Industrial/Milton Coupler” or a “Universal Coupler” on your air source in order to connect to the MORRFlate Quad 4 Tire Inflation Deflation™ Kit.

If you need a coupler, then add one on when you place your order. Our I/M Couplers come setup on a 1/4″ Hose Barb. All you need to do is push the barb into your air source hose, and add a hose clamp to it. If you don’t have a hose, then remove the barb, and screw the coupler onto a 1/4″ Male NPT connector for your air source. Make sure to use nylon pipe thread tape!

Q: Does the MORRFlate Quad 4 Tire Inflation Deflation™ Kit come with a gauge included?

A: It does not! The tricky thing about air gauges is that they only read accurately in the very middle of the gauge. So, if you have an analog dial gauge that reads from 0-100 psi, it will only read accurately at 50 psi. The further away from middle that the gauge gets, the further away in accuracy it gets as well. So, on a 0-100 psi gauge, if you are airing down to 10psi, the reading on the gauge could be upwards of 5 psi off at that measurement!! Crazy right?!

This means that if you use dial gauges, you will need to find 2 gauges that work for your intended tire PSIs. If you normally air up to 45 psi, then you will want a 0-90 psi gauge. If you normally air down to 5 psi, then you will want to find a 0-10 psi gauge.

The easiest way to fix this problem, is to get a MORRFlate Digital Gauge. They are rugged, accurate within 1% across their entire range, precise to the tenth of a PSI, and can handle upwards of 250psi before being damaged. We do not include it with the MORRFlate Multi Tire Inflation & Deflation™ Kits because some people would still prefer to use one of the 15 gauges they have laying around and save some money. But you can always choose to get one or have one built into your kit when you place your order.

Q: I have other questions! Where can I get them answered?

A: You can ask them in 4 different ways! Please allow 24-48 hours for an answer, as we often find ourselves getting lost in the mountains for a few days at a time.
