Slow drip from pool equipment

[jz2753]

I have a Jandy JXI pool heater and have noticed a drip from a piece of equipment connected to the heater. I’m not really sure what to call the part, but the close up in the picture of the black part connected to the heater is where the drip is coming from. Maybe 1 drip a minute at a guess.
Any ideas what the issue could be or can anyone identify what this part is called?

Tks

Maybe the drain plug seal is leaking. There’s probably an oring on it. Or maybe it’s not tightened enough. Give it a gentle twist clockwise to check.
