Video Transcript for Air Lift Union T-Piece Review

Today we're gonna be taking a look at Air Lift's Union T-piece for quarter-inch air lines. And there are two main reasons you may want this unit when installing airbags. You can use it when installing a compressor to tee off and give yourself a manual inflation valve or like we're using it here on this truck to take the left and right side airbags and bring them into one so we can fILL them up simultaneously.We've got ours installed here so our inflation valve is coming out the center of the tee and the two coming off the sides go to both our left and our right side airbags. You may prefer this setup if you just want to quickly air up your airbags simultaneously. Now, you are going to lose the ability to air the up independently from side to side. That's gonna be important if you're trying to adjust for uneven loads.

You may want them to be different on one or the other. But if you're not really using it for uneven load purposes, this is going to make airing them up and deflating them much quicker if you're constantly hooking up and removing the same trailer over and over that doesn't need left and right load leveling.On our Air Lift compressor systems, it already comes with one T-fitting to allow it to air out both bags simultaneously, but if you want to add a manual inflation valve to it, you'll need a second T-fitting here. This can be installed anywhere between your air compressor and airbags in line on any of these quarter-inch airline hoses that's gonna be run. You just simply place it in between and have the center one go out to your manual inflation valve.Now, we'll show you how you connect and disconnect airlines form this fitting. It's a click-connect fitting, so you simply just push them in.

But to release them, the end here actually slides inward, and I'm using a eight millimeter wrench to do this. You just need something that'll push in on both sides. So, it pushes that in evenly and that'll allow it to release, and the hose just simply slides out. To put it in, you simply just push it in. And I like to kind of push it in and pull out a few times to make sure it's fully seated.

And as you can see here, if I'm not pressing in on that collar there at the end, I cannot pull this out. It automatically locks itself in place. And that completes our look at Air Lift's Union T-piece for quarter-inch airlines.

I first purchased the Air Lift LoadLifter in an attempt to help reduce trailer sway and handling of my truck when towing my travel trailer. The far exceeded my expectations. Having the ability to get both my truck and my trailer completely level has made an enormous difference in towing. These air bags are not designed to reduce trailer sway, but being able to tow with everything level and having anti-sway mechanism is the perfect pair. I only wished I had found them earlier and there would be been several less "white knuckle" driving experiences.



by:

The air bag kit was easy to install, works great, but it was missing four - 3/8" nuts. The air bags tremendously improved the ride when pulling our RV. It all went together with the hitch we bought from etrailers a couple of years ago. Service is great and the people follow up. You all are our go-to company for truck and trailer parts.



by:

Air Lift air springs are good and dependable, use them for the last 25 years on three pick-ups always worked great. My complaint would be against the lousy packaging which came with two or three holes and all messed up, luckily all that was missing was one washer.



by:

just getting done putting my 5000 Justable air springs put them on about three hours I didn’t have any left I did them on the ground so that’s not too bad I’m gonna be sending some pictures along with us so thanks very much and I hope they work



by:

Works great. Used in air lift system and never drops pressure. Just have to be sure tubing is firmly seated during install


Comments
Awesome product. Maintains system pressure in all conditions

I wish I had ordered this when I ordered my Air Lift kit, but I didn’t. So I had to pay for shipping, but it arrived very quickly and I’ll be installing it today.


Comments
The “T” connection is still working as it should. No leaks, and it’s so nice to be able to fill both Air Lift bags at the same time as well as deflating them together.
David - 01/16/2022

by:

Works as expected and helps me fill both bags at one time. No leaks. I drilled one hole next to license plate for the ahead we valve. When I eventually get a compressor, I’ll drill another hole below it for the quick connect air chuck.



by:

Purchased this along with my air lift system, made it very simple to adjust the pressure with a single port.



by:

I used these on Firestone airlines. Worked perfectly. No leaks after a year of continuous use.



by:

Well.... I was watching a how to install video from etrailer. First the video was excellent. I saw this product and wanted to have it before I installed my load lifter air bags. I ordered and BAM. Here it is 2 days later.


Comments
The push “T” connector is working well. It is nice to only use one air hose to fill both air bags. You don’t have to work to adjust equal air poundage on both sides.

The fitting made it a breeze to equally inflate air bags!
Item as described and was easy to install.



by:

Very easy to use and it did not leak much better that the plastic one that comes with the air bags.



by:

Good to go easy to install work well I used the no drill mounting plate which was not made for this kit only had to drill a few holes and it worked well all instructions were easy to follow ( installed on 2004 F250 super duty)



by:

First, I can’t say enough about etrailer and Amy E. and all her help. I will be happy to highly recommend etrailer to all of my camping friends and people I meet at the campground. They were extremely helpful and very diligent in keeping me informed of my order status.

The airlift load lifter 5000 has performed fantastic. I got home Thursday evening from work and started the installation project. I did the process in my driveway in 2 1/2 hours. The instructions were very clear and easy to follow. If you have the capability I recommend lifting the whole back end of the truck and removing the rear wheels for installation. I was able to work over the rotor while kneeling instead of laying underneath the truck the entire time. I also purchased the airlift union tee and put a single Schrader valve in my bumper.
I left the next afternoon for a weekend of camping and was happy to see my truck sitting level while being hooked up to the camper.
Thank you again Amy E and etrailer



by:

Seems to work better than the ones that came in the Firestone air bag kit they were always leaking. These do not



by:

Awesome piece that made the job that much quicker and seems pretty heavy duty.



by:

I can't believe these things work. Like magic! Two airbags into one inlet.



by:

Jim M this product was as ordered functions as it should I am very satisfied would order again

I am very pleased with the union T and the load lifter kit ,when the compressure and wireless controller arrive ,at that time ,I will have it installed and get some pictures ,till then THANKS .



by:

Used this fitting for tying air lines together for Air Ride airbags on my 2018 Chevy truck. Simple install , great performance.


Comments
My Air Bags are great, this fitting allows quick adjustment
Olin B - 07/08/2021

by:

On the 2019 ram classic, the installation process takes approximately two hours! Tires and wheel well liners have to be removed to provide total access to the top of the springs.



by:

I used this tee, seeing as I did not need independent side to side leveling. Worked great.



by:

Got this tee so my Firestone bags would be equal. The same tee from Firestone was twice the price.



by:

Just what I needed to complete my install, quality and no leaks I recommend this to anybody installing air lines for whatever.



by:

Purchased this to make it easier to install my airlift air helper. This item works like a PEX connector, simply insert the air line completely and voila! I have had no leaks. I'm sold on this T and so glad I bought it.

Still working perfectly after a year
