Stainless-steel-wrapped hoses take the hassle out of inflating and checking the air pressure of inner tires on dual wheels. Kit is designed for steel or aluminum rear wheels with wheel liners. Hardware included.

Specs:
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 the inner tires on your dual wheels.
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. And the stainless steel wrapping on the hoses helps prevent them from cracking or leaking.
Hub-Mount Installation
The dually inflation kit is designed for steel or aluminum rear wheels with wheel liners.

fast service, professional,this is how you run a company...thank you Larry S
I was pleased with the order and the items I received. But I think I have ordered the wrong type for my vehicle.
Excellent product, fast service. etrailer is great to work with.
Arrived by specified date and product was as expected. I would recommend this store.
Excellent product. Came exactly as ord ered.
Easy install, no leaks, very satisfied
I just installed them today. They where for a hose that was leaking. So far, so good. I wish they came with the different degree's of adapters like my last set. Lucky I still had some around. Otherwise everything is good.
I've had them installed for about a year, now, & have had zero problems. I've heard people say, "don't use extenders, they leak". Well, either they don't know what they are talking about or they've never had these.
Easier to install than expected. Watch the install video, it covers all of the steps necessary to install. Only tedious step is getting the extension started to turn on the inner valve stem. Much easier to air up inner tire. This kit replaced the original rubber extension. Now I will add TPMS.
This product installed simply and easily and works as expected. I replaced faulty valve stem extensions on my motorhomes dual rear tires. I would recommend it.
Not sure, everything in the package looks good but it will be awhile till I can get them installed.

Product works very well so far, mounting is still tight and there are no leaks. Like how it allows such easy access to the inside dual.
Been using these for about a year now and they work great. I check my tire pressure often and only need to all air once in a while. Certainly no more than before I installed them and lot's easier.
These valve stem extenders worked perfectly for my situation. I have used them for about 4 months so far and my tires are all holding their pressure.
Back in 2014 I owned a Class C motorhome for which I bought a TPMS of the type with external sensors on the 6 valve stems. Over the next two years I had endless problems with air leaking from the several rigid types of valve stem extenders that I bought. Then, in 2016, I upgraded to a Class A motorhome and transferred the same TPMS to it with one big difference: Purchase of the Wheel Masters WM8005 dual tire inflation kit from etrailer. At one year and 10,000 miles later, there has been NO leakage from the inner duals, and I am very pleased with this purchase.
Everything that's needed (parts) was included in the kit. The install was a breeze. Drilled out the old grommets to center the extension.
The product appears to be good quality. However, the package was still in Mo. after eight days and I needed the product prior to a trip. I ordered another set and paid $[XX] to have it shipped via UPS so I would have it delivered in time. Well, the original order finally showed up after 11 days and now they’re saying that I have to pay another $[XX] to return the first order to them. Not a good way to get customers.
I rec'd my dually wheel / hub kit. Item#WM8005 came as a complete kit, plus it got here in only two days,which is great for coming by "carrier pigeon". I am totally pleased with the product, it fit as req'd . The service I rec'd from etrailer was GREAT the phone representative (Alcain) was VERY helpful, she is totally knowledgeable of the product lines she represents. She answered my questions, and took her time to explain the differences of the products I was looking for. Some over all I am PLEASED with etrailer and yes, I will recommend them and continue to use them.
Thank you
With UPS shipping the package arrived on time and intact. I installed on the two inner wheels of my Fleetwood motor home. So far, no leakage and installation wasn’t bad at all. Would certainly recommend.
etrailer provided the normal excellent advice, ordering and shipping information. The product installed as demonstrated in the etrailer video. Great experience. I will keep using etrailer.
