Does anyone know the correct term for the rubber part that the ac hose attaches to along the firewall? The rubber part is attached to the ac metal "piping" connection on the firewall. I removed it, dropped it in the engine into the vast unknown!!!

 

are you talking about the rubber groment the the closes the hole in the firewall or are you talking about a coupler that connects the metal and the plastic parts of the ac together?

 

A coupler that connects the metal and the plastic parts of the ac together. Thanks for the termonolgy. Auto parts store had them in an assortment pack.
