AC hose leak which part?

I've got a leak on my ac hose line from the condenser. Found these three parts, not really sure of the difference. Anyone know?

You sure it is not just an O ring?

 

Not 100% sure a dealer told me it was the hose when I broke down traveling and they fixed the air pumps. They wanted a bit much and two days longer than I had for the part to come in.

 

10-4, A/C O rings are cheap. Try that and vacuum the system down. If it will not hold a vacuum then proceed until it does hold a vacuum. Just my .02

 

Will do, i'm gonna give it a thorough look today and see if I can get a better idea, hopefully some of the ac oil points me to the right spot. Then hopefully it's just an o-ring.

 

Make sure you have the proper amount of oil in the system so the compressor will be lubricated. When you get the system recharged. Let us know what you find wrong good Luck.
