I have heard that the stainless steel valve extensions leak and that they can be troublesome. I don't want or need that aggravation. I have also heard that there is a type that can be mounted within the wheel and are supposed to be better. I don't know anything about either one of them but I do know that I want to do the right thing and install the best extensions that I can get so that I can be vigilant in maintaining the proper tire pressure and not deal with the PITA that it is now to check the air in the tires.
Please tell me which is the bst way to go here!
Much appreciated!

I have the stainless steel ones on my rig and they don't leak.I know the plastic ones do.

I had braided stainless steel extensions on our previous rig and had no problems. My current rig also has stainless extensions on the rear inner dual. I also had solid stainless extensions on the front of my old rig that produced a better angle for checking air pressure and filling the tires. I am looking for the solid ones for my outer duals and front wheels for our current rig.

Look at Dually Valve Stems from Borg Tire. Bit pricey, but I would buy them again without hesitation. http://www.borgtiresupply.com/owner/duallyvalve.pdf

@ jzick We have had those on our last two coaches and for my money they are as good as you can get.

V2B Inflate Thru Valve Cap

Dually valves and these make checking and filling tires as easy as it can be. I like this set up on my own rig.

Used them on my previous three units from a Toyota Dolphin through the Tiffin and only had problems with one and I think it was damaged during tire replacement.

If an extension leaks it wasn't installed properly. There is an o-ring on the tire side that seals the extension to the wheel stem. If the o-ring gets pinched or sideways, the extension won't seal (and the o-ring may be ruined). Careful installation, & checking for leaks and you should be good for the long haul.

If you ever have tire service on duals, the service outfit will probably remove the extensions; make sure they put them back & get them seated so they don't leak.

My MH had the braided wire flexible hose extensions when I purchased it. I installed new tires and the tire shop suggested Stainless Steel extensions, but I stuck with what was there.

Big mistake! Three times on a trip from the West Coast to Fl I had inside tire leaks. First time in Bullhead City, AZ was not bad, they found the connection to the rim loose and only charged me $15.00 to fix. Next time was at a Truck Stop, but had to call a Mobile Tire Repair truck to come there. Same problem, but that time it cost me $135.00. Third time it cost me $45.00 at a tire shop as since it was the same problem each time I guessed that the flexible hose was whipping around and causing the seal nut to come loose. Had the Wire Braided Hoses left off and never had another leak on the way back to the West Coast.

And I have since added the stainless steel extensions.

My braids lasted ten years as did my tires with no problems what so ever. Heard a lot of warning about them but never had a problem.

But when I installed new tires I went with Dually Valves because I could not seem to do anything around the duals, wash, check air, wax etc; without cutting myself on the supports holding the braids away from the rim. Too much stuff on the rim.

So far with Dually Valves I am unscathed.
