Valve stem rotates (2025 Update)

Micky, Micky, Micky - you get yourself into the finest pickles, don't ypou???

The valve sem is a pull-in friction fit seal. It HAS to be able to turn. Aslong as it isn't leaking, don't worry about it.

However, you DO need to be able to remove the cap - - - -

Metal caps are MUCH more likely to stick to the brass thread of the stem. Cut the old cap off completely and replace it with a new plastic one. Put a wee touch of silicone grease on the thread to help keep it from sticking again. (grease - NOT sealer -- - -)

I DO use metal caps, myself - and I DO lube them. - but plastic will be just fine for you and be less likely to catch you again. While yoiu are at it, remove and lightly lubricate the others too.

Yes, if only because it will then be possible to check the tire pressure again.

No harm in trying superglue.

Yes, they tend to corrode more.

Yes.

It's true that it's a pull in friction fit, but I've never seen one turn when trying to remove the valve cap, valve, etc. Micky must be out of friction.

SOME metal caps are aluminum. Some are zinc.Some are actually steel or stainless Some are brass. Some brass are tinned, some are raw.Some are nickel plated.

Silicone grease actsas a dialectric - uncoupling the 2 metals in the case of non-brass caps. It also seals the threads from moisure.

Sounds like you pissed someone off and they super glued your caps on. Do you still have the "Obama 2012" campaign sticker on your bumper?

ROFL

That's a good one.
