Default A/C leak

Hi guys,

I haven't had working A/C in a while so I thought I'd give recharging a try and see if a leak would be visible. I see it leaking from the High pressure pipe going into the compressor. Does this look like something I could fix? I'll google around but thought I'd check in here in case someone else has had the same problem.
Thanks.

At what part of the pipe do you see the leak?

Looks like its all coming through then end of this pipe that is bolted on the compressor. I wiped it dry and can now see new liquid leaking out of here:



BTW sorry about not showing the pic before. I had posted a couple of pics and thought they were available to be viewed.

I read that the system needs to be vacuumed or depressurized? If it's all drained out could I just disconnect that pipe and replace the o-ring, then recharge? I'll check the service manual to see if they have this procedure.

Yes exactly that's what you can do but then it can be vacuumed down to see if it has any leaks in the system. After that it can be pressurized with freon and oil

I do commercial hvac and it's the same with a car hvac it needs to be in a vac before it can be charged but if there's a slight leak and there's still gas in the system you can buy some time and too off the charge with a can of 134a from auto zone the one with the leak stop might be a good idea too if there's a bigger leak bring it to a shop they will pressure test it to find leaks fix them then vac it and if it holds a vac of 500 microns it will be ok to charge
