Hotop 4 Pieces Valve Stem Extension Stainless Steel Braided Extenders, 6 Pieces 45 90 135 Degree Brass Extenders for Cars Trucks Motorhome Trailer Rv Trailer Vehicle(7 Inch, 12 Inch,Silver)

I used them on my 2024 Denali dually, I installed them several months ago and so far no issues whatsoever. Very satisfied.

The perfect solution for airing up the dually tires. No need to remove the hub caps/wheel simulators to gain access to the valve stems, especially the rear tires. No more squeezing your hand through the small openings to reach the inner tires. I used the 7" hose for the inner rears, the clamp takes some effort to install but with the large side of the clamp towards the middle it doesn't interfere with the hub cap. I used the almost v shaped tube for the outer rear tire and the slightly angled tube for the front tires. Well worth the effort to install these and no longer getting cut hands trying to air up the tires with the hub caps on. Turned a 30 minute ordeal into a quick and painless job once these are installed. Good price and good quality.

Haven't used yet but everything was as described, will update when installed.

Quality product. Several comments from others about slow leaks that I would like to help with. 1_Install your extensions with Teflon tape or paste. 2_If you use the angle extensions, use tape or paste on those items. Position them for the angle that you need, then tighten down again with pliers. 3_When adding your braided extensions, use the same tape/paste. Tighten down, attach the other end to your valve holder plate or use the holders supplied to your your wheel. If you have anything loose or that will vibrate loose, then you will eventually have leakage with any extensions. I set these up on my RV rear dually tires and drove over 400 miles. Checked the pressures and everything has held for over a week now with no leakage. I will be installing GUTA TPMS sensors/system on these and will be able to monitor the tires through this device.

Se rompen con el tiempo, tienen que tener cuidado porque bota todo el aire de las gomas cuando se rompe

fits with some adjustments on our rv tires

Not too hard to attach and an awesome addition for my RV. I won't go without these.

In theory, the clamp system works but in practice, it doesn't have any flexibility to be mounted in such a way that makes any sense. I tucked the hoses in behind the outer wheel for now and will see if they stay put or if i need to come up with another solution. The 45, 90, 135 fittings are great. I added a bit of blue lock tite to the valve stem threads just for good measure. Used the 45 degree on the front wheels to kick the stem out for ease of use.

Excellent produit!

I hoped this would make it easy to check and fill the dual tires on my RV but they kept working loose and the leaked. I had to call roadside assistance twice. Also they don’t work with any of my presume gauge or filler that works ok on all other tires. In the end they cause much more trouble than any convenience you hope to get.

Leaking and unusable. Dumped them.
