Valve stem extensions

[MSHappyCampers]

I found these with the mounting brackets I need, but the extensions are waaay longer than needed!

I use the Dicor braided extensions. Not sure if they are advisable on rubber tire valves.

They take more length than I thought when I installed mine. The ones above are for 16 to 19.5 inch INNER DUAL rims.
How about this?

I don't remember where I read this, might of been the manual even, valve stems are to be installed directly across from each other when wheels are mounted on the hubs. For what it's worth, mine are that way as well. Never a problem.

I just talked to a lady at Wheel Masters. She has agreed to sell me the individual pieces, two 7" flexible hoses, two L brackets, and two nuts. Total cost will be $22.56 plus shipping!

My neighbor is out of town until next Monday. I will measure when she gets back but I think the 7" will work fine!

I found it,

Care and Service of Passenger
and Light Truck (LT) Tires
Including Tire Replacement Guidelines and
Recreational Vehicle Applications


Chapter 4:


Valves20 - Metal valve caps with rubber seals are
recommended for RV applications due to generally
higher operating pressures. The metal cap with a
rubber gasket provides a seal that a plastic valve cap
may not provide.
Bolt-in (clamp-in) metal valve stems are
recommended for RV applications. They MUST be
used when valve extensions are installed because the
extra weight of the extension or hose can distort
rubber stems and ultimately cause loss of inflation.
When dual tires are mounted on a vehicle, they
should always be installed with the valve stems 180
degrees apart (for example, if one valve is at the
6 o'clock position then the other should be at the 12
o'clock position).
It may be necessary to install an extension hose with
a bolt-in (clamp-in) metal valve stem to check
inflation on an inside dual tire in some applications.
It is recommended to use extension hoses with
stainless steel reinforcement and external braiding
as protection. The ends of the hoses should be
securely attached to the wheels so that they cannot
come loose while driving. If the holes in the wheels
are too small or in the wrong place to be able to
check inflation pressure on the inside tires, this
situation must be corrected before travel.

Thanks Bob! Who published that information?

Hope it works for you Everything you wanted to know and then some

First off, I have to wonder about the rubber valve stems already on the MH. There are standard "passenger" snap[in rubber stems and "high pressure rubber stems. You can see the difference in my blog post on Valves. NOTE the passenger snap-in stems are rated for max of 65 psi.

If you have wheel "simulator" hub caps you can see how to install with the end "L" brackets here

The above shows my TPM sensors installed. Depending on the simulators, length and angle of the bolt in metal stems, you may need to bend the simulator a bit to be sure it is not rubbing the hose.

If you only have center caps as below, This is what the set-up can look like. Again with "L" brackets. Note this picture does not show the external TPM sensor.


I have about 30k miles using extenders as seen above which are like the "Wheel Master" seen on Amazon.

IMO TPMS is the #1 safety addition to be placed on every RV (MH or trailer)

I have a post on tips to follow when using extenders if you want to learn more.

Dually Valves are the way to go. Yes, more expensive than braided extensions but more reliable in the long run. Dually Valves (like Borg Valves) require the tires be removed from the wheels to install the valves but well worth the investment. (Note that I have a 2016 Itasca Navion - Mercedes 3500 chassis).

As I mentioned, the owner is out of town this week, but I think I remember that the rubber valve stems may be too close to the outside tire (or wheel) to use the flexible extenders without pushing the stem to the side a little. If so, is that a bad thing to do?

I've been looking at the 45-degree solid extensions below. It seems to me that that might be the simple way to go. I believe they would put the end into or close enough to the hole in the outer wheel to allow airing. Do you think they would have enough weight to cause problems with the rubber valve stem? Thanks for your help!

The 45 and 90 degree extenders ARE prone to loosen/leak if they are not anchored. Tried em
