Freon leak from low pressure port

I have a 2000 F150 V8 Triton and wanted to recharge ac, when cap from low pressure port removed I heard a little hiss and once off discovered a freon leak. Wondering if anyone can help with how to repair? Is there possibly something I can tighten or does the condenser have to be replaced? The AC use to work great, slowly lost icy air and obviously due to leak, thanks in advance for your help.

I don't know but I would assume it is much like a shrader valve on a tire where you can unscrew, replace, or tighten it?

I had the same thought, I used the tire valve tool and attempted to tighten it but all it did was turn and didn't seem to get tighter.

If you turned the Shrader valve and it didn't tighten, that would suggest that the threads are stripped and that the line (not the condenser) needs to be replaced in order to cure the leak.

Otherwise, recharge it and put the cap back on. The cap should seal it enough so the leak is, at least, slowed down to a manageable rate.

The low pressure port is located on the side of the condenser, not part of the line like the high pressure port on the engine.

That's different from my 2002 because my low pressure port is close to the firewall.

Then that would be the accumulator, not the condenser. The condenser is in front of the radiator.

Maybe you don't have the correct tool to tighten the schrader valve? It may be a different size from the tire valves?

Aftermarket accumulators are only about 20 bucks at Rock Auto. The hassle is the system needs to be evacuated and recharged from scratch.
