Cooling line threaded fitting

[Dmart29]

I have this R&D head that does not have a cooling line fitting installed on it. Does anyone have / know where to get one of these ? Basic plumbing shops don’t have them. The thread is 1/4”

Auto parts store should have them.

That's crazy, every one around here has them

Better hardware stores, better auto parts, like NAPA.
Worse case, I can ship to you on Monday

Here’s a question for ya, where that threaded plug is on the head can I put a cooling line to there? Why would it be plugged off
