Valve Stem Extenders,4Pcs 7Inch/180mm Dual Flexible Stainless Steel Braided Valve Stem Extensions,6Pieces 45 90 135 Degree Brass Valve Adaptors for Car Truck Motorhome Trailer RV Trailer Vehicle

Installs great on Class C RV with dually rear wheels. Also using on the front wheels since they are difficult to access to filling air too. Fit seems to be good so far for sealing. Time will tell but believe it is fine because when tightening the fitting the rubber seal seemed very secure and stable.

Great collection of extenders for duallys. I used these for the outside tire on my rv's dual tires. IT was impossible to reach the air fill before. Now so easy

These work very well, apart from one issue I found. The provided clips, installed as shown in the manufacturer picture (picture #1), will rub against the valve body, eventually rubbing through the metal and causing a leak (picture #2). I like these enough that I bought a second set and this time I'm using a piece of rubber hose to isolate the valve body from the clip (picture #3).They'd be 5 stars apart from this issue, and hopefully if you're reading this you can avoid the problem altogether. They are easy to install, seal.well, and the metal-clad hose seems to be very high quality.

Works great

If you have a truck that has tandems on the rear these things are pretty darn handy and that's exactly what we use them for just to make life easier when you get old and decrepit

The angles are not right for a dually rear wheels

Aloud me to check and fill my RV tires with less hassle.

Waste of my time. They fit fine but functionality does not exist. My automatic air pump could not get the pressure to stabilize and is accurate down to .5 psi. No matter how many times I would reattach hose it would never get the right pressure. I took them off and instantly got my pressure dialed in first shot. These are a waste of time and money honestly. Don’t even bother
