  • Inflation Kit
  • 22-1/2 Inch Dual Tires
  • Hub Mount
  • Wheel Masters

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


Features:

  • Inflation kit lets you easily check air pressure and inflate your vehicle's dually tires
    • Relocates inner tire's valve stem to outer wheel and extends valve stem on outer tire
    • No crawling on the ground or reaching for valve stem on inner tire
  • Stainless-steel-wrapped, 2-ply rubber tubing with nylon braiding
    • Durable wrapping helps prevent hoses from cracking or leaking
  • Simple hub-mount installation with included hardware
    • Hoses attach to valve stems on inner and outer tires
    • Brackets mount on steel or aluminum rear wheels with wheel liners
  • 4 Hoses included
  • Made in the USA


Specs:

  • Application: inner and outer tires on 22-1/2" - 24" dual wheels
  • Overall length of hoses with straight valve extenders: 15"
  • Length of hoses with 90-degree-angled extenders from end of valve to 90-degree bend: 10-1/2"

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

  2. Attach the hoses with straight valve extenders to the valve stems on the inner tires.
  3. Attach the hoses with 90-degree-angled extenders to the valve stems on the outer tires.
  4. Run the hoses to the outer wheels and attach the hoses to the hub-mounted brackets.

The product is exactly what I ordered, great quality and fit. The shipping dates seemed long but after contacting etrailer they were sent out in time to be installed before I have to leave town.

Just what I needed for my motorhome. These flexible hoses wear out just like anything, and I recently put new tires on my coach so I knew it was time for new valve extensions as well. Make sure you get them installed tightly so they don't leak. Easier said than done on the inside dual tire, you'll need to get under the coach likely to be able to get to it with pliers from the backside. My only recommendation would be to buy the extensions BEFORE installing new tires and have the tire shop install the new extensions with the new tires. I'm not as young and flexible as these valve extensions, so installation wasn't as easy as it would have been 20 years ago.


Comments
Still working well after a year. I did have one that was slowly leaking, 3-4 pounds over a week. I tightened it up and the leak stopped. Dont assume they stay tight because you put them on tight. Still very happy with the purchase.

I am very pleased with these tire inflators. The product is well made And the price was not outrageous. Order was filled in a reasonable time. I would definitely order from this company again.

Purchased the Wheel Master valve stem extenders to the replace the original Wheel Master extenders that came with the motorhome from the manufacturer when purchased it, at the time, 15 years ago. Hoping to get another 15 years of service out of these new ones. Only issue was the box etrailer put the product in was to small and the original packing was folded or bent to fit the shipping box, causing the OEM packaging to break open. Several of the small parts were lost in the shipping. Luckily the old parts on the motorhome wheel simulators were still usable.

Even though I only needed one extender to replace a faulty one, it was worth the money to buy this better quality one piece extender.

When I contacted them, the immediatley cancelled the orginal order and set up a new one with the key error corrected and I got shipment soon after. Great Customer Service
