Cheap Alloy non-TPMS tire valve found
 

I'm slowly getting the items together for my new wheels and came across these:

$3.02 a piece, only in bare silver. They use on o-ring seal so they should be re-buildable for cheap. About half the weight of steel ones, the caps are aluminum also. The topnut design design gives you some reach in case the stem hole is recessed.

I ordered 8, they arrived in 4 days. They are a tire service supply company but you don't need a wholesale account.
