Where to buy Enei style metal valve stems for the car and trailer?

[IG.]

NOT made in China, too. This is NOT for the bike - it's for the car and the utility trailer to track the bike.

I need 1", 1.25", and 45 degree angled like those shown in the below ebay items. Also, would those work for 60-70 psi of pressure? Also, do I need to replace rubber grommets once in a while, or those are good forever? Any other suggestions.

I am switching to those because I will be using screw-on sensors for the tire pressure monitor.

1" example: ebay item.

45 degree example: eaby item.

I orderd from her ebay store short metal valve stems for the bike a couple of days ago. She doesn't seem to carry anything for cars though.
