WheelMaster Wheel Masters 8029180 180 Degree Valve Extender - Pack of 2

They work wonderfully. I put them on my motor home tires and drove 2500 miles with no leaks.

These do not work on our Jayco Class C as they are for rear Aluminum wheels, NOT steel wheels. I can't find on the description where is says this so be careful what you order.

I rate this 5 stars because it is exactly the right product to access the rearwheel valve stems on my RV. I don't know why they don't have these installed at the factory. After talking to professional truckers, I ordered these and they solved the problem. I use TireMinder pressure caps on the RV tires and this made the installation and use very easy. They are high quality and do not leak.I also purchased the straight extenders for the front tires. Both work perfectly.

No matter what I did, these caused my outer dually tires to leak constantly. I was going from 80 psi to less than 30 psi overnight! I replaced the o-ring with high quality vitrol o-rings and no change. To make matters worse, it was nearly impossible to actually get air to flow into these to reinflate my tires. I would highly recommend you look elsewhere - these are useless!!! DO NOT BUY!!!

I used these extenders on the rear outside wheels on a Winnebago Vista Class A unit. Wheel openings made it difficult to get the angle right to fill these tires so I added these 180 degree extenders to simplify/address the issue. A bit tight to work on getting the extenders threaded on and secure. Other reviews had mentioned "loosening" and air leakage when driving, so I added "Locktite" to the threads when attaching. So far, no leakage. That's the only reason I gave it a 4 star vs. 5 star rating as I am in the "wait and see" mode to determine if I experience any leakage over time.

Good fit.

Ordered the wrong angle

beautiful uniform construction with bright chrome finish. well worth the price.
