Anybody recognize these? Smaller one is not a fuel injector oring. 97 up cam sensor?? Bigger one is too small cross section for water pipe. Job is done just wondering what these are.

Maybe 420A parts got thrown in for some reason? Those appear to be exactly for the camshaft and crankshaft sensors, which are always included with 420A head gasket sets. Not sure how this could happen, but it appears that way.

I'll post specs below if you want to compare.

If they're 420A o-rings, just throw them in the trash . Really cheap for anyone to buy so not worth selling or even trying to give away.
I like to keep a handful of spares in a plastic baggy. Even the ones I thought I'd never use end up getting used somewhere. I wrench around too much though.
