Yes, that's the heater hose.
Mine split on the way home from work, many uears ago. Started pumping a jet of water out, straight into the cat. I noticed it when I stopped at some lights turning onto the M4 & was enveloped in the cloud of steam from under the bonnet!
+1 for Rockauto, One of these should be what you need, but verify that it is the right year/model etc:
JEEP -> 2008 -> WRANGLER -> 3.8L V6 -> Heat & Air Conditioning -> Heater Hose / Pipe
My other hoses lasted until last year. The heater hose split as the clip near the firewall that holds it in place broke & it chafed through on something near the back of the engine bay. Early in the life of the car & it was replaced under warranty.
