I Smashed My TPS Valve Stem!

Could the red ring have been in the valve cap as the seal that supposedly makes the cap tight enough to hold pressure if the valve core parts start leaking?
What is a "stuck needle?"

I hit the valve stem and see the two pics for the results. The red plastic ring came out of the valve stem and the cap was split in two and the stem was damaged per the pic.

My initial thought is to leave it be. I checked the tire pressure without letting the air out of the tire. Through a stuck needle. So Im thinking its fine.

Is it? Do you anticipate problems? Should I have the shop fix it?

Thanks!

You may be right about the red ring being part of the cap. I’ll check the other caps in the morning. If the body of the valve Itself was bent It might stick open when checking the pressure or adding air. But it doesn’t appear to.
