Video Transcript for What to Know About the Air Lift Union Tee for 1/4" Air Lines

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.

The air lift union tee is working good now for 4 days since being installed on my 2012 Honda Odyssey! No complaints here!

The Airlift system is still working great! I keep 10 pounds of air on it even when not pulling my trailer because ok the stability it provides. ??

@Vincent Perfect! You want to leave at least 5 psi in the bags at all times....


by:

I received this kit and it was incomplete. There was a hole in the box in the bag of hardware was open. Not a big deal though, as only a couple of bolts were missing. The problem came upon trying to install this kit on an F150 2023. The left side has the ABS and brake lines along with a breather line for the axle. There is simply not enough clearance to put the product in without cutting up, the clamp that holds the ABS line and brake lines. I’m not sure why they did not make this kit to fit over the spring Shackles instead of the axle? Pretty sure engineers could have figured something out. I installed this on a 2012 Ford and it went great because it went over the shackle bolts. Only took about two hours. I’ll probably return this and just go with a spring helper unless there is a easier kit for installation.



by:

Worked great to allow me to use a single air fitting for both Air Lift 5000 helper springs!



by:

I installed this system on a buddy’s truck about a year ago for towing his travel trailer and he loved it. So when I got my 2023 F150 I knew that I would eventually want a set. That time came as soon as I put my 1500lb golf cart in the back!
System was super easy to install. However I suggest removing the rear wheels. Made the job so much easier. I went with a T for the air lines so that I could utilize easy, balance bag fill and empty. There’s already a hole in the license pocket of the rear bumper in a great location so all I had to do is drill through the plastic cover. Pictures are with 70 psi in the bags.

Really like the air bags and acc. Ni more sway or bounce

Gary

Perfect with the camper behind me I eliminate bounce



by:

I have had rear suspension airbags on the last 5 trucks I have owned. There is no better system to control weight roll of a load in the bed or sway control pulling trailers.Be sure to order the air line "T" which does not come with the kit so that "T" can be connected to use only 1 air fill location to balance your load.
No more need for sway control bars to struggle when pulling your camper with this set up.



by:

Easy to install, directions were spot on. Just installed them so can't give the product a fair review. I installed ot with a t so both airbags have the same air pressure, I'm not dealing with uneven loads so I thought this would be the better way of doing it for me. I had some extra wire harness tubing left over so I user it for my air line to give it some extra protection



by:

Product is good, packaging was horrible. I get that it isn’t a dozen eggs, but when you throw metal objects in a box and send them 1000s of miles with our wonderful shipping companies, boxes rip and parts fall out. One of the u bolts was taped to the box, another was hanging on by a thread, and the union tee was missing. Please, put loose parts in a bag, don’t just throw them in and tape it up.

I will definitely let our shipping department know how this arrived. We will also have a new union tee sent out to you. Watch for an email from us.

This item was missing from my order. The shipping notice said it was shipped but item was not found in received package. I need this item to complete my planned installation.

Absolutely, you do! I am sorry you are still having to wait! I am looking into this to make sure we get you the parts you ordered.



by:

I use air bags under my rear axel to level my truck after hooking up my truck. This fitting connects the two sides so both are always inflated with the same pressure It's extremely easy to set up, and it just work, no fuss and no leaks



by:

Purchased air nag system for my 2022 F350 super duty. Entire system is awesome made towing my fifth wheel smoother.



by:

Product works as advertised. Great customer service. Installation videos are spot on. Fast shipping.



by:

When I called etrailer I was able to speak to a sales person, I told the person what I was looking for and they helped me with my purchase. It was a great experience and I would recommend etrailer.



by:

great customer service was very helpful when ordering my parts for my truck i was very pleased never a disappointment thank you



by:

Easy installation, great quality, fast shipping



by:

Them fittings are exactly what I wanted now I can pump everything up at one time



by:

Cannot be beat for the value and performance-
Towing
a 7K lb boat with Independent suspension on the Toyota Sequoiq, this eliminated the sag and actually rides better inflated even without the trailer weight. Installation is easy and straight forward. Jack the vehicle up and use zip ties to make the bags smaller and tighter to slide inbetween the springs, then cut ties!



by:

Definitely a must for the gen3 tundra… make sure to get the compressor at the same time….



by:

I just want to say that e-trailer is very easy to deal with I appreciate the fact they get right on the products that are ordered and have them shipped out as soon as possible. Also a few months back I had an issue with a break assembly that was shipped out and they had the new brake assembly sent out to me within three to four days. I will continue to use etrailer to purchase parts from for my RV repair business. Thanks again and I definitely highly recommend using a trailer.



by:

Everything I have ordered from e-trailer has been very good quality and I have been happy with everything.
The staff that answers the phone is very knowledgeable and hang with you until you get exactly what you want.



by:

Excellent service and super fast shipping. Etrailer is awesome to deal with! Very good quality but didn’t use yet. Plan on adding second air port for when truck camper is on.



by:

Work amazing. I pull a trailer every day for work. Big difference with these airbags installed. Rides a lot better.

Works well. Did not install duel valves to fill each side individually. Looking back may install fill valve for each side.
