Need name of this AC hose (picture)

Hello, I have a '95 Firebird and I need the name of the metal hose that is on the lower left hand side of the pic running between the battery and radiator cap.

Some how there is a small leak near the radiator cap in mine and I'm either going to buy a new one or find some type of epoxy to patch it.

Any tips?

looks like you are talking about the line going to the AC condenser. If it leaks, you have to take it to a professional AC guy. They have to fix it and give u a freon charge. I just cracked the lower hose in mine taking out my radiator. So im actually gonna call around and find out how much it is to recharge the system.
