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.

The kit also includes two 45-degree-angled valve extenders to make checking and airing up your front tires even easier.

    Video Transcript for Wheel Masters 4 Hose Inflation Kit Installation

    Today we're going to be taking a look at, as well as doing a quick installation of, the Wheel Masters Four-Hose inflation Kit for 16-inch to 19 1/2-inch dually wheels, part number WM8208. We're here at our rear dualy wheel. In this particular case, we're on a motor home, but these Wheel Masters Dual Tire inflators will fit any set of dual wheels, whether it be a pick up truck or a motor home like we're on here today. We have a couple of different hoses. They are stainless steel-wrapped hose. This hose here, the straight one, is designed for the inner dual wheel, which can be a real pain to try to fill up with air, especially if you notice the tire is down as it's way up in there. For the outer wheel we have our valve stem and it's actually going backwards, so we have a 90-degree. Again, this is stainless steel-wrapped rubber hose.

    Our 90-degree fitting will go in there, as well as two clips, one for each hose that will go and connect here to the edge of the rim. On this particular vehicle, it doesn't have any wheel covers or wheel simulators, but these will work with wheel covers or wheel simulators. Depending on your size of your wheel, you may need to slightly bend the bracket a little bit once installed to make sure that it accommodates the bend here at the outer edge of the rim. The kit also does come with two nuts that will secure the hoses to the brackets, go through like this and then install one of the nuts down on it. That way it's nice and tight, and then it also comes with a chrome valve stem cover. Let's go ahead and show you how to put them on here at the rear dual wheels. We'll begin with the inner wheel.

    I don't know if you can see it way up in there. Now that we have the extender hose screwed onto the valve stem on the inner wheel, we then need to choose a location here on our rim that our hose will line up with and go through like that. We can then go ahead and add the nut on. Now that we have a bracket on, we can take our wrench and snug down the nut. We then need to choose a location, install the clamp, tap it into place. Now that we have our hose and our clamp installed, we'll go ahead and put our valve stem cover in place.

    We'll then move over and we'll install the outer wheel valve stem. This one, it's the outer wheel, you'll notice it's got the bend here on the end. Right here is our valve stem. We'll need to reach in. Once you get this one on, we may to take a wrench to tighten it down the rest of the way to make sure you don't have an air leak.

    Go ahead and add our bracket in, put the nut down. Once we've got our clip in place, we can go ahead and make sure the nut is tight securing the hose to the bracket. Add our valve cover to it, and that's all there is to it for the rear wheels. Now we've moved up here to the front wheel, and for the front wheel it comes with this little metal extender. It's got a bend to it and this will allow you to bring your valve stem out a little bit more so that you can get the air chuck in there and fill your tire up and monitor the tire pressure a little easier. This one, again, just threads onto the existing valve stem. Thread it on and tighten it down. Now with our extender on it, it allows you to get in easier and add air to your front wheels. Depending on exactly your wheel design, at what angle you want to add the extender. Now this Wheel Masters Four-Hose Inflation Kit does come with enough hardware and hoses to do both sides of the vehicle, so you can do both rear wheels on the dually, as well both front wheels. If you're using these with wheel covers, the bracket clamps to the side of the rear wheels before the wheel covers are installed. That'll do it for our quick look, as well as installation of, the Wheels Masters Four-Hose Inflation Kit, part number WM8208.

    - WM8208

    We have a class C Motorhome with a Ford chassis 16" rims and the two outside rear dual rim hoses are so tight in length that you can hardly get the brackets that hold the hoses to hook onto the outer edge of the rim. One of the front rim extensions will not take air. 500395

    After a year and 11,000 miles the extenders are still working fine. No leaks and easy pressure checks.

    Works great! Installed on gooseneck tandem axle duals. So much easier to check air pressures and maintain. Would buy again. 371140

    - WM8208

    Great set of tire valve extenders. They all have hex nuts for a wrench instead of knurled nuts for tightening onto stems. 111182

    They are still doing great, Have not needed to remove them for leaking, like the other brand.
