Checking and maintaining proper tire pressure is important for ensuring a safe, smooth ride and maximizing fuel economy, but it can be a real pain with dually tires. The Wheel Masters inflation kit takes the hassle out of checking air pressure and inflating your dual tires.

Two hoses extend the valve stem location of the inner tires to the outer wheels. This means no more crawling around on the ground or blindly reaching for the valve stem on the inner tire. Two 90-degree hoses are also included to make it easier to access the valve stems of the outer tires. And the stainless steel wrapping on the hoses helps prevent them from cracking or leaking.

Hub-Mount Installation

  3. Attach the hoses with 90-degree-angled extenders to the valve stems on the outer tires.

Haven't installed yet but they appear to be good quality extensions. Replacing an original set so should be an easy install.



Working as advertised. Satisfied. Easy install and looks great.


Fantastic customer service from James R. Very satisfied with my experience. Refreshing to speak to knowledgeable and friendly folks here who don't "sell" but point to pros and cons of offered products. Thanks!


These worked great to replace my old inflators that had developed a leak. They never lose air. Very well made.


Just got these in the mail yesterday, installed them today on a 2017 Forest River Forester (E450 Chassis). Just had to pry the wheel simulators off on the duallies and then needed to drill some holes for the brackets then pop-rivet them to the wheel simulator. Airing the rears is MUCH easier now. Next I'll be adding the EEZtire TPMS for monitoring tire pressures/temps while going down the road.


Great customer service. Product as described. Shipping and tracking shipment very efficient!


I had these on and older truck and they worked very good. Did not fit my 2016 3500 Ram according to directions. Installed them on an angle.


I bought these hoses to replace an old set of the same on my RV. Ive had two of the old ones start leaking, one at the crimp, and one at the oring seal to the valve stem. The old ones were put on when the coach was built in 2002, so Im not complaining about the slow leaks. These hoses make checking and adding air easy. The new hoses look like they have improved the ends and the connector to the valve stem. Checking pressure should be done often, and these hoses make it easy. Only thing better, is to have a monitoring system for pressure and temperature so you can watch from the dashboard. Im thinking about that one........

Hoses are still working fine. I did add a tire presure monitoring system, and the sensors hood up easily to the hoses. I did use stainless screws and nuts to mount the brackets because the rivets had worked loose on the original install back in 2002 Screws and locknuts hold much better.


Good procut and good quality. Some installation needs modifications.


The parts worked great and wasn’t hard to install just needed the tool to drill and pop in brackets. My only suggestion is to pay for express mailing. It took two weeks for the postal service to get it to me


I used these on my 2007 Chevrolet 3500 dump truck, they are very easy to install, and on a chrome or stainless wheel simulator blend in pretty well. the only thing i didn't like about them is that the extnesions themselves ride right against the 4 decorative ovals in the wheel covers, which made me worry about them eventually rubbing through, so I positioned the mounts on the center cap where they would have the least tension or stress and wrapped a piece of EPDM rubber roofing around the braided stainless line, applied clear silicone to it and put a pipe clamp on it to ensure it wouldnt move to protect if from any friction.
I figure I can suffer a little bit of looks to not lose air out of a tire while loaded. lol
All in all they do work as they should and make it 100 times easier to check air pressures and add air if needed, if the ovals in my simulators were a little bigger I think they would probably fit better, they do fit great on my 2009 Delta dual tandem gooseneck equipment trailer no complaints on there at all :)


Item was received in short order. Instructions were detailed for installation. I pop-riveted the extension to the hub cap. This completely stabilized the extensions from any movement. After installation we have completed several trips totaling about 1000 miles and have had no loss of air from the rear dual tires on our class C motorhome. My tire pressure monitoring sensors connect without any issues. Just recently checked the air after being in storage for three months and tires have not loss any air. Very satisfied with the the 4 hose inflation kit.


Received my air valve extensions today. Well made and should last a long time. bought these for my RV. 25 foot with duel wheels . Will make checking air pressure much easier. Easy to order. Arrived in a reasonable amount of time. Very satisfied with the purchase and the service from etrailer.


Finally got around to give you my review on the Wheel Masters 4-Hose Inflation Kit. I installed the kit on my 1998 31 ft. Ford Motor Home. It works great. I should have done this years ago. Installation was very simple. Thanks for a very good product.


thanks for the fast turn around, my
husband will put them on the back tires on our motorhome so he will be able to put air in without taking the tires off. thanks again for the wheel masters 4-hose inflation kit dually-hub mount-wm8001


The 4 hose inflation kit worked out great for the rear dual tires on my motorhome. The tire shop did have to put shorter valve stems on the outer tires to get the extensions on. But I was replacing the tires and needed new stems anyway. The kit was delivered very promptly as promised. This kit will make checking tire pressures and adding air much more convenient.


This product makes it so very easy to check tire pressures on dual wheels. The struggle to check and fill the inner tire is eliminated. This is the second motor home I have installed them on. It’s really a time saver.


" Easy to install, with no special tools" This is a under statement.
1. Right angle drill will be needed.
2. pop-rivet tool will be needed.
3.Decor wheel liners made of stainless steel require very sharp drill bits.
These were installed on a class A motor home with 19.5 dual wheels.
The outside dual had to be removed and rotated 180 degree, because both valve
stems were in the same rim opening.


etrailer shipping was fast. My gripe is with the manufacturer. They should print on the packaging that this WM8001 requires a small 90 degree angle drill to drill the necessary 8 holes in your chrome hub cover. Shame on them! Luckly, one of my friends has one of these angle drills.


Exactly as advertised and what I wanted.


Of all the parts I bought, this was bad. One of my tires went flat, had it not been for a passerby at the gas pump I would have ruined a tire. Then, you people wouldn't make my purchase right. This happened the second day on the road. Poor quality and poor guarantee.


Product is as described. I purchased this item because one of my rear dual tires was missing the kit.

As of this review, I haven't physically installed this item but it looks identical to the existing kit installed on my motorhome. All parts present and build quality looks excellent.


1 line was leaking

This inflation kit is covered under a one year warranty. The manufacturer will reach out to you.


Quality product with all the necessary attachments.


I off road on the beach in a Dually pickup and these are absolutely needed, however they leak all the time. Installing them although not hard, getting them to actuate the truck valves is a royal pain. I wish there was another option


I received my order on the date promised!
you very much.
