Pacific Dualies 18100 Max EZ Air 7-Inch Braided Stainless Steel Valve Stem Extension Kit for 16-19.5-Inch Dually Rear Inner Wheel

I have monitored these for 10 days with no loss of air. Another brand I bought leaked from installation.

We recently purchased an RV and this makes checking air pressure so easy. Seems to be excellent quality and were easy to install.

we couldn't air up the inside tire so we replaced the tire and then found out it was the valve stem extender. I ordered these and installed it myself. it was very easy. Just make sure you get it tight.

good product

They fit just right on a 2006 phaeton deisel pusher with 22.5 inch steel wheels and 4 inch oval cutouts and stainless wheel covers.The wire clip for the loose end fits nicely on the steel wheel at the 4 inch cutout under the stainless steel cover.Sturdy construction and fast shipping.

easy to install, but the bracket that holds the flexable line does not hold it steady when you fill with air, have to hold with channel locks to make it work.

The site says these will fit duallys but the spring retainers supplied with the exstenders can not be used on 2004 Ford factory F-350 custom alum.wheels because the factory alum wheel openings are tapered and too thick. I was able to install by plastic cable tieing the extenders to the metal valve stems in thje outer wheels. On my truck the valve stems are located in the same position directly opposite each other. I also used the 135 degree valve stem extension which worked when tieing the extenders to them.

Excellent purchase. I purchased these for use on my class c motorhome. They were easy to install and made the checking of air pressure in my tires so much easier. This gives me peace of mind.
