Works just like a grease zerk fitting and make sure you wipe the tip of the Alligator caps before adding air. I would be concern if they are good for RV PSI tires.

Why is that? I figured it wasn't any different than removing and reinstalling a valve stem cap.

Is there any reason not to stack extensions? That is, can I put a 45 degree on my valve stem, then add a 6" extension to that? Has anyone done that? I've never tried it, but don't see why it wouldn't work.

Just remember that you will also be increasing the chances of having the extensions leaking.

I was wondering that same thing. I may try it or just buy new flexible ones and see if they work better than the ones I have.

I have suggested people run a 10% cushion on air pressure. That eliminates the need for constant messing with the pressure. Tires should loose less than 2% (less than 1.5% is better) per month , adjusting for changes in ambient.

Using your TMPS cool tire morning reading and recording the ambient temp too I think that if you make a chart on monthly temp & pressure you will see what is really happening. If you loose more than 2.5% you may have slow leak. Soapy water spray around valve stem base (where it mounts to wheel) and around the TPMS or extenders should show ZERO bubbles. Not even any small ones.

Valve cores are not really "adjustable" but can be over tightened which places them too deep for some TPMS sensors to open the core. I have a couple posts just on valves.

Long valve stems

I suggest that if you are looking for long "bent" metal stems you ONLY get them installed by a Truck Tire dealer. Preferable not just a "dealer" as anyone can sell tires, but a "company store" or a store that is part of a large chain as they are more likely to have a selection and actual training on proper installation of truck valve stems.

With long stems it is also important to remember to not just press the end when adding air or checking pressure as you can generate a lot of force on the joint between valve and wheel. Always support the stem or hose extension with your other hand even if the stem or hose has a hard mounting as you can loosen the mounting point too.

Thanks for the info. You bring up a good point about messing with the air pressure. I don't mess with it but I guess it would be easier knowing I could just pull off the tpms and add air as needed. Right now I have to squeeze my hand between the wheels to deal with the inner dually and it's not the easiest thing in the world.

I purchased Alligator V2B Inflate through Valve Stem Caps. These are very well made and add just enough length to get a dual head chuck inside the rim to measure tire pressure. They are self sealing, so no valve cap is needed. I have used these for several years now with no problems.

Used them by the hundreds on a large truck fleet. Never had a problem with them. I never could get people to replace regular caps-they either tossed them or didn't bother to check them at all.

Valve caps & cap extenders

If you do not use TPMS sensor or have "flow through" sensor you still should use metal valve caps that have good internal "O" rings. Valve caps do two jobs. 1. help keep air in if the core is leaking and 2 keeps dirt out of the core which has a very small valve in it. See HERE.

If you use the "aligator" flow through cap be sure you always clean off the end as you may end up blowing dirt into the valve core if you add air and there is dirt on the end of the cap.

Check Why valves leak

Valve Extensions
