Speaker 1: Today we're going to take a look at the Firestone union connector for quarter-inch air line tubing. Now, this push-to-connect union fitting allows you to connect two quarter-inch air lines quickly and easily. This union will also provide a simple air line disconnect with no need to cut the line. This union connector includes two push-to-connect fittings, one on each end, for the Firestone quarter-inch air line tubing. Again, this part is for a quantity of one union connector, and the overall length on it end to end is right at one and a quarter inches. But, that should do it for the review on the Firestone union connector for the quarter-inch air line tubing..

Always happy to do business with you. Great products and excellent service thank you


Working on the airbag suspension system on our RV, I need replacement hose and some couplers to replace a line that was leaking. The new line worked flawlessly, didn't need the couplers but will keep them in case of a roadside emergency.

It has continued to work flawlessly
Scott - 06/06/2020


My original order was out of stock so etrailer suggested an option that I determined would work and could be shipped immediately. I cancelled my original order, placed the new order and had my items in a couple days. Couldn't have worked out better.


Very happy with order!


All these quick-connect air fittings are expensive for what they are, but they're super easy to use. These unions in particular are about as expensive as air fittings get, but you can make use of scrap air line that would've been useless before. You have to weigh the cost of the line vs. these fittings, however.

Cut the line square, and these things are fantastic. Super fast installation and zero leaks.

Still working great, even after a round of winter road salt spray. These are so handy for installation, Id love to keep a few around, just in case.

very good connector air tight and easy to use


Amazing little connectors! I cut out the bad crushed section of my air hose and slide that into place. They work like a million bucks! Whoever designed these deserves a raise! No leaks whatsoever. Thank you.


Simply put Awesome!
I sure wish I knew
these were out there years ago. No more brass fittings that leak with the hose.
These were a perfect fit for my application.
Now when I need to access this area it's quick and easy.


I think it was 8 months before I used these. They work perfect as expected and the service was great as always from etrailer. :)


Excellent personal customer service. When one item was out of stock from the manufacturer, an etrailer rep called me personally several times to explore options. Then once the order was finalized, shipping was expedited as they knew I needed it for a weekend project.


I bought this to repair an air bag line that a squirrel has chewed.
It was easy to use and air tight. Took less than a minute to install.


It's super fast shipping awesome service great video description


Products replaced a T-connection that was leaking air. They worked perfectly, and I am very satisfied.


Your product prices, info and services rock! Instructions are the best idea I've seen.

Thank you


Terrific fast service. Exactly what I ordered and came faster than I thought it would.

Works perfectly. No prblems

  • Firestone Air Bag Connector Needed for 1/4" Tubing

It is used to connect two 1/4" air line tubes and allows for a quick disconnect without having to cut the line. This comes in a quantity of 1 but we also have part # F3079 which is the same thing but in a quantity of 10.

  • Is There a Straight Connector for 1/4" Air Lines on the Air Lift 1000
    Yes, you can use the Firestone Union Connector for 1/4" Tubing # F3079-1 to connect two 1/4" air lines quickly and easily. This will work for 1/4" airline regardless of if it is from Air Lift, Firestone or anyone else. This comes with 1 fitting, so you would need to order 1 for each set of lines you are wanting to connect.

  • What Size of Air Tubing Does Firestone Air Suspension Enhancement Use
    The size of air tubing that comes with the Firestone Ride Rite kit part # F2299 is 1/4 inch. For 30 feet # F9416. If you need to connect two cut tubes together you can use the union connector part # F3079-1 as well.

  • Air Line Union Connector for 1/4 Inch Air Line Tubing
    We certainly do! You'll need part # F3079-1 which is a Firestone part, but it's also compatible with the 1/4 inch air tubing used with by Air Lift air helper spring kits as well. Like any of the air line push-connectors, a good leak free connection depends on the air line cut being perfectly square. Use a sharp utility knife or a dedicated tubing cutter like # AL10530, as snips or docks will partially crush the tubing resulting in leaks.

  • How Often Should I add Air to my Firestone Coil-Rite Air Helper Springs on my 2015 Toyota Prius
    When using the Firestone Coil-Rite Air Helper Springs Part # F4136 on your 2015 Toyota Prius you should not have to add air on a regular basis. I sometimes see a slight pressure loss when it goes from hot outside to cold and you'll have to add a bit to get it back to pressure similar to the way a tire on a vehicle fluctuates up and down slightly with weather. If you are adding air on a regular basis to the bags to maintain your desired pressure then you have a leak in the system and...
