Hello I've notice the aircon connector where you refill the ball bearing part with gas has small air bubbles coming out.

 

So is there anything good I can use to clean the ball bearing filler?

 

The next option can you detach the filler part from the metal pipe and are there any replacements?

 

Thanks

Any work on the A/c system needs to be carried out by a qualified person so you need to go to avA/c specialist.

 

So can the connection be removed or cleaned?

 

I'm only repairing it my self as the cost of paying to repair not worth it and the job easy to do.

No it’s part of the pipe if I remember correctly but   some cars have a Schrader type valve which can.

But even still the refrigerant  would need removing by a professional as it’s high pressure and illegal to release into the atmosphere as it’s so damaging to the environment and your health it can cause frostbite along with other things. 

Its a dry break coupling made for specific quick connectors, different sizes for the high and low side circuits.

 

The couplings should have screw on dust covers, these if fitted and tightened will stop any leak, its not their primary function and many garages seem to lose them when they recharge, if the Schrader valves dont leak then it makes no odds but the dust that gets in usually ensures that they will leak after the next  time a coupling is connected.

 

Get some covers, screw them on and forget about it, with luck at the next recharge the valve will seal again.

 

If you saw the bubbling after removing the caps that can be quite normal as a minute amount of gas will pass the seal and sit in the cap at system pressure, it wont boil off until the cap is removed.

 

hope that helps!
