Metal Lines and Clamps what are they?

[Brian W.]

I have a small leak of some fluid coming from a line and clamp area under my 996. I am not sure what the fluid is and if this is a clamp with an o ring inside. Can someone please help me by explaining the function of this. I have attached a picture that I have circled in red the area.

thanks

Those are a/c lines. The fluid is a/c fluid. Is your a/c cold? You can see the parts here.

thanks for the quick reply. Yes the ac is cold. It was just a minor bead of fluid by the clamp. Do I have to drain the system to replace the o ring. I am not sure if this is part of the charged system.

Yes, all those lines are under pressure with a//c on or off. The only way to fix it properly is to evacuate all the refridgerant, replace the bad parts, then vacuum and refill.

Thanks again for the information and help. It's nice to have a project car; never boring.
