Anybody recognize the markings on this fitting?

This isn't the actual fitting that I need but the roll mark was easier to get a picture of

It's not Parker. I was in their store yesterday and they had no idea

That looks like a newer/ish company

This came off an '89 Peterbilt

Possible that the company isn't around anymore, or was sold to someone else

The fitting I'm looking for is a test probe port that goes on top of the thermostat housing

1/8' NPT threads with a 1/8" NPT plug in the top to close it off. There's a grommet inside that seals the probe when it's inserted

I can find all sorts of test ports in 1/4" NPT but nothing in 1/8"

For now I just replaced it with a 1/8" male to female fitting with a 1/8 pipe plug in the top to seal it off
