Hello,

The A/C line can leak at the joint due to a bad O-ring or it can leak at the hydraulic joint, it is where the flexible part of the hose connects to the metal part.
If it is leaking at the O-ring joint, then replacing the O-ring should take care of the issue.

It could be helpful to use a dye to determine the exact leaking spot.

Here is a helpful guide on A/C leak detection:

Before the line can be removed the A/C system needs to be discharged.

Let me know of any questions.
Thank you.
