Introducing the MORRflate Stubby Manifold – Initial Impressions & Review

The MORRflate Stubby Is Modular Manifold That Doesn’t Require Fixed Hoses – 2-Way Air System or 4-Way

MORRflate specializes in multi-tire inflation/deflation kits that are designed to make your life easier. No one likes to bend over with a tire gauge constantly checking only to find inconsistent results when they’re finished. With all of MORRflate’s systems, tire pressure is equalized across all connected wheels – taking the guessing work out of the equation.

I’ve used both the classic gauge and digital style deflators and none have been this simple, and have almost always had to do double checks for my desired PSI. The specific kit we’ll be taking a look at is their new Stubby system.

What is The Stubby & How Does It Compare To The Original?

Morrflate Stubby Kit

The MORRflate Stubby differs from the main kit in one major way: modularity. This feature makes storage much easier because the air hoses can be detached from the manifold unit. Other additional benefits are if you have different length sets of hoses for multiple vehicles, you can utilize this one manifold.

If you want to keep your front and rear tires at different pressures, the stubby allows you to only use the “duo” hose set vs. the quad system. One last key feature is that if for whatever reason, you break either the manifold or damage the air hoses, you would be able to replace only the broken part and avoid having to buy an entirely brand new system.

Setting Up

Connecting Air Hose to Morrflate Stubby

Since the stubby doesn’t have permanently affixed air hoses, you’ll first need to connect them to the manifold.

Using The Stubby

Morrflate Stubby in OFF position

Operation of the Stubby is dead simple. Turn the red manifold lever to the side to stop airflow, and turn it down to allow airflow. I found it best to keep the lever in the side position so that when I attach the air chucks, air doesn’t start coming out unintentionally.

Connect MORRflate Air Chucks

Connecting Air Hose to Tire Valve

With the manifold connected and level turned to the side, connect each air chuck to a wheel. To lock the air chucks in place, just slide the outer ring mechanism down towards the valve.

Chuck Slide in the Back Position

I like to store the air chucks with the locking mechanism (collar) slid back, that way I can attach and secure them to the valve in one motion.

Ready To Go

With all tires connect to the system, you’re ready to air down super easy and quick.

Airing Down

Decreasing Air Pressure with Morrflate Stubby

Once you have everything connected, turn the level in the down position to start airing down. The digital gauge was pretty true to what my TPMS system was showing so that alone is going to make the air down/up process super easy. Airing down doesn’t take long (I only go down to about 20 PSI from 38PSI), so keep an eye on the gauge.

Airing Up

Morrflate Stubby with Air Compressor

The air-up process is pretty much a rinse and repeat of the air-down process. Start with the manifold level in the side position before making your connections. The only extra step is adding your air compressor to the setup.

Connect Your Compressor

Air Compressor with Adaptor

Depending on which compressor you’re using, you may want to check out MORRflate’s store for an appropriate adapter. What these adapters allow for is to connect the manifold directly to the compressor, rather than run the air hose between the two – creating a rat’s nest of air hoses. The time it takes to air up will vary widely depending on which compressor you’re using. In my case, I’m using a Viair 400P and modest 285/70/17 tires – so airing up from 20PSI to 38PSI takes less than 10 minutes.

MORRflate Vs. Addressing Each Tire Individually

Inflating a Tire with Morrflate Stubby

A big question people have is whether the MORRflate + setup time is actually quicker than airing down each tire individually. When I first hit the trails with my buddy, he had the original MORRflate and I had a typical single tire deflator with a digital gauge. Time-wise, we were about even. Accuracy/consistency-wise, we were much different.

What I found was that after running around each tire and thinking I was done, I check the TPMS, and not only was I not aired down nearly as much as I thought, but each tire was at a slightly different value. This kills my OCD, and I would gladly break out the MORRflate system just for consistency alone.

Elevate Your Airing Up Game

Airing up is a whole different story. MORRflate all the way. My compressor is pretty quick filling up each tire individually, but it requires me to constantly turn it on and off to check pressures, causing unnecessary wear and tear. With MORRflate, I only need to turn the compressor off once to check the pressure for all 4 tires because the system also equalizes all of them.

Storage Bag

Morrflate Stubby Storage Bag

MORRflate has a pretty slick storage bag for their system. The bottom of the bag has mesh to allow water and dirt to fall out after using it on those muddy trips. The front has a zippered pocket to store the manifold and any compressor adapters you might have.

Keep Those Air Chucks Mint

Air Chuck with Rubber Cap

Each air chuck also has a rubber cap to help minimize any debris that might get inside them, which would be bad for your valve stems.

Overall Impressions

Morrflate Stubby Complete Kit

I like anything in life that provides reliability and consistency (that’s why I bought a Toyota in the first place). This is what I appreciate about the MORRflate system, all without having to crouch down obsessively watching a gauge at each tire (your back will thank you). I’m a fan of the lime green air hoses, which greatly increase visibility if you ever need to use them at night or in the mud. All of the hardware feels solid and has satisfying “clicks” with every connection.

What are your thoughts on MORRflate or other multi-inflation/deflation systems? I wasn’t quite on board initially and it seemed like an unnecessary expense. However, after using it on a few trips, I have changed my mind and now I’ll never look back.

Do you need a small whip connector when using a Power Tank or similar C02 for refills so it won’t freeze the manifold?
