RVZONE Stainless Dually Valve Stem Extenders 16‑19.5", RV Truck Trailer

Checking tire pressure on inner dual wheels used to be my least favorite part of trip prep, but this kit completely solved that headache. The quality of the components and the ease of use make it worth every penny. What I Loved: * Solid Build Quality: The stainless steel braided hoses feel extremely durable. The 2-ply rubber tubing inside gives them great flexibility without any risk of kinking, cracking, or leaking under high pressure. * Complete, Versatile Hardware: The package comes loaded with everything you need. Having both straight and 90° extension hoses, plus 45° adapters, made custom-fitting my 16" wheels straightforward. The included V-shaped, 90°, and flat brackets give you plenty of mounting options depending on your wheel design. * Massive Time Saver: Bringing the inner tire's valve stem out to the outer wheel means I no longer have to blindly reach through wheel slots or burn my hands on hot brake drums just to check PSI. It makes pre-trip safety checks effortless and ensures I’m maintaining proper inflation for optimal fuel economy. Installation & Performance: The threaded connections mated cleanly with my factory valve stems without stripping or leaking air. Once secured with the included brackets and hex hardware, everything stayed firmly in place with zero play or rattling down the road. * Verdict: If you own an RV, fifth wheel, motorhome, or heavy-duty truck with 16" to 19.5" dual tires, this kit is an absolute essential. It adds peace of mind for highway driving and turns a frustrating maintenance chore into a quick 30-second check. Highly recommended!

Wonderful product that I took to Discount tire which they installed on the dually tires for my RV with no charge.

Purchased these hose sets for our E450 class-C motorhome. Removed the rear wheels and installed these. Aired up the tires to the recommended 80psi and sprayed with soapy water before reinstalling. NOTE* I saw no leaks at that time* Parked the motorhome in the building since they were predicting sub-freezing temps for a few days. When I went to get it out after about 10 days, I open the door to find all the rear tires VERY LOW! Reinflated and checked to find ALL FOUR OF THE HOSES WERE LEAKING! The pics here were after spraying soapy water on and leaving for under 30 seconds.... so it's serious leakage. Returning this junk!

Great quality. Fit perfectly on my Thor motorhome. Works great on front wheels and the dually too

After a month being installed. I have no leaks and the air pressure has been steady at 110 psi. Definitely remove the tires to install and clock your valve stems 180 degrees apart for easier hose routing. Going to wait till I can see how their hold up to road salt before I pay more the my fleet.

Worked well

Everything is perfect. I received the item on time and same what I ordered

One of the two 90-degree extension hoses leaks from the factory where the flexible hose connects to the elbow. I'm worried that more leaks are coming with use. If the hose detaches from the connection the tires could go flat very quickly and cause a serious hazard. I only needed two of the four extension hoses, so I was able to use a spare strait hose as a temporary fix. I'll be watching my tire pressure monitor system to detect any additional leaks as I'm driving. In the meantime, I've requested a replacement set so I can return the one defective hose. I'll update if there are further issues while driving.
