Valve Stem Extensions Leaking Air

[Roy Francis]

I have a set of Pressure Pro sensors with valve stem extensions all the way around my MH. The ones in the front leak after a month or so. This happens when I take the sensor off to check the air pressure and if I did not take the extension off all the way, the tire would go flat. I have tried several brands with the same luck. Any help would be appreciated. Thank you.

Hi Roy,
What material are the extensions made of (ex. rubber or metal)?

[Roy Francis]

Hi Gary, the stems are made out of steel. They came from the factory this way.

Also Gary, the extensions are made of steel.

What it sounds like is happening, is that when you unscrew the Pressure Pro sensor, the extention is unscrewing a bit too.

If this is the case, how about using Lock-Tite on one of the 2 joints so that either the extention comes off with the sensor, or stays put?

Make sure you don't get any Lock-Tite into the valves though.

Extensions are many times troublesome. I finally gave up with leaky extension and went with Borg valves. These are brass extended valves . It requires tire removal to install, but was well worth the hassle to me.

JoeH, I have'nt heard of Borg valves. Can you supply more details? Thanks, HarveyP

Try taking the time to use a pair of pliers to hold the extension as you unscrew the sensor. JMHO!

What John posted is what was happening to me. I tightened the extensions with a little torque from a pair of pliers. Also, I use pliers to hold the extensions, in place, when removing the Pressure Pro sensors.

I want to thank all who answered my call for help. I forgot to add that I do hold the valve stem extensions with a pair of pliers but the extension leaks at the very end while screwing off the pressure pro device. Any suggestions as to why?

I don't have any kind of tire pressure monitors, however:

The device has to open the inlet valve in order to monitor the tire pressure. If it is holding the inlet valve open while it is being unscrewed, it will leak air until it is totally removed. If it is faulty, it would probably allow air to escape while it is being installed.

[JerryForwood]

It will always do that.
The pressore pro has a release built-in. It has to release the pressure into the devise in order to read the pressure. It is acting just like a pressure gauge that you stick on, only you notice it more because you are screwing it on instead of just holding it on.

Are your valve extentions the "woven type?" I have tried two sets of these and on both sets, I had leaks -- I have finally replaced them with US Made extensions (available at Camping World) that are solid SS. No more problems.
