Extension Valves on Inside Dually, Yes or No

BORG Dually Valves! I was a skeptic and a procrastinator for several years. I had to add air often and it was difficult to do. I bought ours at Six Robblees, a truck/trailer enthusiast shop, about eight years ago and they have been absolutely wonderful. I added Air-Through Caps so no unscrewing. Just go wheel to wheel. I can check six tires in well under a minute. ***AND*** They rarely need air!

Nope. Just a hassle that seem to leak

Tire-Man. Great product/service - no leaks.

The best on the market,that are the original,are Tire Man.

Chuck is the original designer of these an he has been around for years. If you have any questions just give him a call, he is always happy to help. Any others are just cheap reproductions of the original.

The kit looks like This it is for all 6 wheels,they also come with flow-thru valve caps so you don't even need to take then off to check the pressure.

Here is a list of all the products he sells.

They are compatible with all Tire monitor systems.

I don't have a built in TPMS on my clipper, so I added these Cat Eyes to my duallies.

They give a great visual check on tire pressure, have an internal valve check, and lets me fill both tires at the same time. My work uses them on their tractor trailers and recommended them. Being able to easily check the inner tires has been a major stress reliever.

I have the cheaper braided ones that have a screw clamp to the rim. They have been excellent for 2 years now. Previous to these, I had the old rubber ones without any problems. The only reason I changed those were they were looking well aged. Others seem to have lots of problems or dislikes with these.

Our Greyhawk Class C came with the braided ones that Cobra21 mentioned. They worked fine for a couple years. One of the inner tires became hard to check pressure and just wouldn't take air. I removed the hub simulator and then removed the extension. After re-installing and removing a couple times and blowing air through the extender a few times, I was able to get it working again. I made sure the extender was on tight.

They worked fine until we replaced the OEM tires. We had Tire Man's dually valves installed when we replaced the tires. Tire Man's valve stems are great. They put the valve stems at an easily accessible place. Checking and airing up tires became much easier after getting the Tire Man dually valve stems. Worth every penny.

Confusion: Cheap screw-on valve extensions can leak and even lead to running soft and tire failure. Custom formed solid metal valve assemblies like Borg Dually valves need to be installed onto each wheel and do not leak, make checking and adding air easy. No need to remove beauty discs.They stay on wheels and are not changed out with new tire installations. RV tires are not rotated so they stay on same wheels. Not cheap, but worth it if you intend to keep the rig for some time.

Agreed......totally trouble free and maintains constant pressure better than anything I've ever had. When I bought them 4 years ago it was about $150 for the kit and another $100 to have them installed. Best money spent on any mod.

^^^Correct^^^
Some OP's have their home brew work-arounds and that's OK. I wanted to be able to both Check Pressure and Add Air with Any Gauge, Any Chuck, and the custom valves accomplish that.
My second choice would be Braided Airless Extensions. By Airless, they don't open the actual tire valve till we push a gauge or chuck onto the extension. There's a flexible push rod that accomplishes this.
***BUT*** ONLY if the actual Tire Valves are METAL!!! You don't want any additional weight on "rubber" valves, even those "high pressure" ones.
