Hello, everybody, this is Jeff at etrailer.com. Today we're gonna take a look at this Firestone 18' long 1/4 inch diameter Air Line Tubing. Now this airline tubing kit includes 18 feet of red 1/4 diameter tubing. It can be used with the Firestone Air Helper spring systems. Basically, this air line is used to connect the airs to the air springs and allow you to inflate the air springs. Now, this is also available in a 22' long part number.
It's part number F99ZR, and even a 30 foot long part number, part number F9416. Also, we do recommend to use the air hose cutter to get you a perfect cut for a perfect seal on your hose. And that part number is AL10530. All of those items I just mentioned are listed on this product page as a related product. But that should do it for the review on this Firestone 18' long 1/4 diameter Air Line Tubing.

Hey John, sorry you've had difficulties! Two things I'd recommend you check. 1) Make sure the the cut on the end of the air line is cut at a perfect 90 degree angle. If it isn't, you won't get a good seal. 2) When you insert the air line into the fitting, be sure you shove them in all the way until they come to a complete stop. Give those a try, and let me know if that fixes the problem!

I’ve not had a problem at all and that’s from -5 to 105 degrees and over 20,000 miles hauling and towing our campers.
