I also have the cap removal tool that you can buy with it. The cap removal tool does not fit over the hexagonal caps that are generally used in aviation.
I bought this combination set. http://www.cleavelandtool.com/Valve-.../#.Vd8i0E3luUk
Just a heads up!!

Jeez, let us know! I am happy to replace it. We have had a decent number or rejects on these. We make sure that the 'core' is threaded all the way in and not partially out. Then we use the end of a caliper to check the distance up from the end of the tool to the end of the brass core extender. We saw some problems with them a year or more ago, but I have not heard lately (except the two here today). I had thought that we were measuring 100% of these that came in, but will check on that, and on the required dimension.

On the 'hex caps' with the removal tool, we send the tool with three round caps with rubber backup seals in the end of them to replace the hex caps. Did you not receive these? Anything is returnable to us, if you are not happy we want to hear from you.

Mike, I too have the same problem that Dorfie above did with your inflator extension (not the full inflator with gauge). The shaft inside doesn't depress the valve stem, as if it's too short. Any recommendations for a field fix?

Sorry for no reply, I just found out that Gmail was filtering notifications as spam.

Hi Mike,
Thanks for the reply. I bought mine more than 2 years ago. I did not receive any non-hexagonal caps with it. I would really like to get this working.
I will PM you.
Thanks.

For those following the last few replies...

After a ton of digging it seems that the spec. for the valve core is 0.010" to 0.030" recessed from the face of the valve stem.

The company that makes the extensions say that due to thread variations, length of core and tube, and difficulty in measuring, they test each one on a valve stem that is .030 recessed to make sure it works.

I have tested 100% of our stock (as did the mfg.) and they all work. We will be replacing the two customers that we have discovered through this thread that don't work. If anyone else if having trouble, please let us know.

Thanks,
Mike

But what about the valve cap?
 
My problem was that my SJ wheel fairings are so close to the tire that I can't get my fingers up in there to remove the valve cover (the little black rubber dingus to keep dirt out). I made one out of some metal tubing, split it with a saw and again at perpendicular to the first cut. I made the cuts long enough to allow me to bend the tabs outward enough that I can put the "tool" through the hole to grasp, twist and even remove the cap through the hole. Usually, it stays in the tool and can be reinserted by reversing the process.

I didn't see this in the OP but I can't be the only one with the problem, can I?

Cleveland tool
 
Ordered 2 extensions. One for the hangar and one for a travel kit.
Modified the main wheel pants w small door. Used a laser pointer to mark the spot to drill. Works wonderful. Airing tires takes way less time.
I remove the wheel pants every 3rd or 4th time to visually check the break.
Plan on changing to a sturdier liner when these finally fail. I'm frugal that way

If you dig a little at the NAPA store, you will find a rubber (flexible) one just like this one.... It really helps if you can't get a straight on shot at the stem.
