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.

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

    Received in good condition and in a timely manner


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

    They are still doing great, Have not needed to remove them for leaking, like the other brand.
    Ron J - 12/26/2014


    The inflation kit was a good price, were received quickly and fit exactly as advertised. I will not hesitate to use for future RV needs.

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

    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.


    Excellent service and shipment arrived as they stated. This the third order, for my Windsport motor home I’ve purchased form the and each time it was as stated and delivered as promised!!


    Perfect fit replacement for my motor home wheels, but within a few months one of the hoses failed and my tire went flat.


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


    The valve extensions worked excellent,that I ordered from Brendon! Thank you!


    Received my order very quickly! Working on installing the dual tire inflation extenders this weekend!
    Thank you again for your great service.


    It is good items


    Product damaged one one my valve stems on the outside dual. I would like to return product for credit. Just started leaking air and was sitting in shop. Will have stem repaired Wednesday.


    I no longer use the adapters for the front becuse one leaked.
    I had a problem with one of the inner tire in the rear. They are still on but I constantly worry about leaking. They make it easy to fill tires but I always worry about leaking.


    Great product, easy installation. Replacement for damaged original equipment. Hope they last as long.



    Arrived promptly , exactly what I ordered. Replacing old set.




    As described, excellent delivery
