Valve Extension?

I am sure this has been discussed before, but looking for lower priced extensions for the valves on my rear tires. I thought the rig came with them but they did not... suggestions on something that will give me a little more access to check pressure and fill tires?

Buy a truckers air gauge, it has a straight and a back angled head, goes to 150lbs. Then buy same style air chuck. Extensions are a pain and another source for leaks. Next time you get tires, have long stems installed on the duals.

valve extensions

Divine Adventure,

You could consider Cat's Eyes as a way to monitor tire pressure and have a single point for testing air pressure. And, if necessary, a single point of adding air to both tires simultaneously. We have owned two MH and we have added Cat's Eyes to each. It is a simple installation and offers a quick visual check for proper air pressure. Something worth reviewing.

I actually looked into these tire equalizing systems, and i liked the crossfire system better than Cats Eye because crossfire displays both over pressure and under pressure. I bought the crossfire
I could not figure a great way to mount them with my wheel simulators.
They'd be much better on larger class A sized tires I think..... or wheels without simulators

I had the braided hose extensions from the factory on my inner duals, but had lots of problems with them.
I ended up buying rigid extensions and have been much happier. 5-1/2 inch long worked for me.
bought the full rubber flange supports form duallyvalve and extensions form ebay.
I'd like the idea of dually valve stems better, but they require de-mounting the tires

I was surprised that after spending six figures on a class A, did not come with valve extenders. Spent half as much on a Jayco class C and it came with valve extenders.

I went with rubber 6-8" extenders cause someone gave me them to use. Made my own mounts out of a wire hanger and works great, no leaks. Also use the EEZ TPMS which also works great.

On my Sprinter Citation I've been through rigid screw on and braided extensions with nothing but problems. I finally spent the money for Dually Valves all around with TPMs. I've put well over 30,000 miles on mine now with no problems and a lot of peace of mind on the road. The only problem is finding a competent and trustworthy tire shop to do the installation with particular attention to the correct tightness and absolutely centering the extensions through all of the rim holes. If they touch a side of a rim hole, they will wear thru. But, if you are a devotee of complicated tire rotation, Dually Valves are not for you.
