A/c Lp Adapter Needed

[bertman]

Cannot track down leak on a/c system,uv light,gas sniffer blah blah blah,all used no joy
A/c bloke suspect evaporator might be at fault,so gonna try less costly option and try a sealant in system.
basically it needs to go in lp port on compresser to work,but guy hasn't got correct fitting

Where can I get an adapter from or the correct fitting,have tried loads of places and people just

When I had a leak recently, it turned out to be one of the pipes to/from the compressor/dryer.

There are 3 thin walled aluminimumimiumimunmium pipes that have tight radiused bends and apparently are prone to pitting and pin-holing (is that a word?) where the metal has creased on the inside of the bends. See picture below of surface pitting on the right and an actual hole on the left.

The pipes are all available from the stealers but two of them are £80 and the third is £130

I was fortunate that the mechanic at my friends garage took the time to trace the entire AC system. They gassed the system with the dye and found that I had a leaking rad, so when they could not find the correct replacement they had my original one recored

When they regassed the car again, they found I still had a leak they so stripped the car to expose the entire system. They suspected the pipes as they have seen this before. They even asked the engineering company round the corner if the pipe could be welded or patched, but were told the walls are just too thin.

So £80 for the pipe (still not paid for the rad recore so dunno how much that was) and I had an AC that managed 3.8 degrees Centigrade output temperature
