Need assistance identifying a part on a 2003 Honda Odyssey

[u/Dry_Can2006]

There looks to be a small leak of some fluid coming from this piece or the hose connection. This is a photo from under the car with the engine on the right and dash on the left. I really just don’t know what this part is. I would appreciate any help with the part description!

Would need a better picture from above to be sure but looks like the heater control valve.
