All auto parts stores carry them. Never buy metal caps. They tend to corrode and are sometimes impossible to remove without cutting them off.

^ Wow, I never knew that. Truism?
I have metal valve caps on my 50 year old bicycle. Them caps are still okay, no rust no problems.
I bet they're stainless steel "Those were the days..."

"When I was younger, so much younger than today..." I would ride my peddler to the petrol station to top off my tires then continue on my way. Whilst there, I would scan the grounds and find all sorts of goodies Valve stem caps included! Always lying about. Today? Not so much. I find pennies instead Tails up (figures).

Found Ya some plastic ones in the mix. Everyone loves Amazon, right? Or is it Wally World?
NOTE: Wally World has plastic caps right in their auto dept. Aw well, Both places are big hitters in my book.
These choices are at Amazon http://www.amazon.com/s/ref=sr_pg_1?rh= ... 1425533859

I got a package of two from the bicycle department at K-Mart that have small batteries and red lights that come on with centrifugal force.

I usually find caps when i go the air pump at a gas station.

Yep, and on the forecourt of most garages.

I had these on my 2011 PCX

Wonder where I put them? Very well made. Chrome Black n Pearl White. Had the o-ring inside too! Not all do. Check 'em peeps!

I shall go hunting this day.
Thanks for bringing this topic up dog64bull

I can vouch for the corrosion claim. I had put snazzy metal caps on my MINI only to find (after a considerable time) that those caps were not coming off. I didn't have to mess with them for so long because the car had tire pressure monitoring. BUT, because the TPM sensors are in the valve stems, I HAD to get those metal caps off without trashing the stems themselves (replacement stems are very expensive with the TPM sensors). Some very careful Dremel work got them off without too much damage to the threads, and cheesy replacement plastic ones went on. Problem solved and lesson learned.

Whitenoise - you might consider a dab of Never-Seize on the stems. We check our tire pressure frequently (right, everybody?) so there shouldn't be a problem, but the prophylactic remedy is so cheap and easy, why not just do it?

All mercedes cars with TPM come with sliver plastic valve caps. The metal ones corrode on in no time and the valves are £££££.

A bit of grease on the stems as said above helps.

Thanks George for your input. That's a good idea if mine turn out to be a metal. What about aluminum? Would they seize or corrode? I have the stock caps on now. I have to find the dual Alien's first.
Extra...extra! I'm with you on checking our tire pressures. It's how I (want to) roll. My responsibility not to get hurt or hurt anyone else. "Pump up the volume"

thanks 2U2 Ali

If the valves are brass and rubber, which most are , the metal caps aren't really a problem. If there kept free of salt and removed regularly to check the pressures they'll be fine.
The valves for tyre pressure monitors tend to be alloy, so steel caps can have the unfortunate effect of corroding together. There's a technical name for it but escapes me at the moment. It causes the alloy to basically rot away. If you google sacrificial anodes it uses the reaction as a way of stopping corrosion on steel parts on ships I seem to remember.

[GeorgeSK]

I'll bet you are right about the metallurgy, Alibally. The stems I had to mess with were silvery metal as one would expect from alloy. I expect that our scoots' stems are brass, so it is likely no problem with aluminum or stainless or whatever. My tires do loose a bit of air, and the difference in ride is pretty noticeable (especially two-up), so the caps are off on a pretty regular basis.

But if your car has TPM sensors... a little dab might just do ya!
