Leaking connector on heater hose on 1994 4.0L Jeep Cherokee sport

#1

The heater hose that goes from the radiator to the firewall is leaking at a connector. I don’t know what this part is called to get a replacement part. It looks like some sort of a valve because several hose are connected to it. It is a black metal and I can see several small cracks where coolant is leaking.

If you describe this part to the person behind the Jeep dealer’s parts counter I’m sure he or she will be able to find it on the computer.
