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.

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

So far, this T has worked flawlessly. It's ease of installation made me a little wary that it wouldn't, but my airbag system loses very little - if any, pressure.


Comments
Its still installed and holding pressure without any problems.

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.


Comments
Still working perfectly after a year

The Air Helpers are a real bear to install, took me 5 hours and lots of ingenuity but it's done now.. They are a very dense, thick, flexible material that are extremely stiff and don't go easily (a huge understatement) between the coils to lodge inside the springs. They are quite low volume so be careful to inflate small amounts at at time until you reach the desired pressure. Haven't had them under a load yet, but if you manage to get them in place I expect they will provide stiffening as advertised.

Easy to install. Haven't pulled a trailer yet but I think that they will do the job.

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)

works as it should and still holding air with no leaks


Comments
works great. Im very satisfied with them and have had no problems. Enjoy carrying heavier loads without vehicle sag in the rear.

Affordable upgrade that simplified the “T” connection on a single path AirLift install.


Comments
Works well, no problems. In hindsight I’m thinking I should had installed the air springs, not just these s with the dual channel air controller. These single channel one contributes to some suspension sway even though the manufacturer denies the problem.
Galen - 03/13/2021

Thank you for your review. Yes, a single channel will fix your problem.

I installed this T so both air bags that are installed for the rear suspension to help backup the springs when I'm towing my fifth wheel. After a year there has been no air leaks anywhere.


Comments
Still no air leaks and I tow the trailer about 10,000 milesyear.

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



- AL21838
by:

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



- AL21838
by:

I put a camper on my truck. The airlift works great. My truck is back to being level and oncoming drivers don't think i have i have my high beams on. Also when i'm pulling into campgrounds my springs don't squeak anymore. I was able to install myself with a few trips to the auto parts store for some longer bolts due the the 5th wheel Hitch on my truck.

looks good haven't installed but should work great good quality

Great quality product and excellent shipping! Purchased on a Monday night and received Thursday afternoon. Thanks guys!


Comments
So after a year of use on my 2016 Nissan Pathfinder these air bags works pretty good. It will stiffen the ride if you dont let the air down to 5 PSI after towing but they hold their air well.
