    For anyone else who has this problem......

    Turns out it was a bad batch of Green Nitrile Orings.

    I got these with the Receiver from Rock Auto. They were junk. Now I'm concerned that the dryer may be as well.
    I did NOT buy the cheapest receiver. It was about average price.
    Be careful.
    I picked up a replacement set from AutoZone and they were far better quality.
    When you buy Nitrile Orings, I suggest taking one from the batch and stretching it with some force, then using your fingernail, try to pinch off a piece. Im my experience3 today, good quality Nitrile Orings can withstand a LOT more deformation than cheap ones and are far more resilient and better at sealing. The feel more rubbery than the cheap ones to me.

    The ones from Rock Auto were fragile and seemed to break and crumble easily.
    The set from AutoZone was VERY strong and resisted breaking and crumbling.

    Also, the metal gaskets can be a bit of a booger to get on. It seems the hole is slightly smaller than the flange on the hose.
    The way around this is to use a deep socket that fits over the flange and use it to evenly press the metal gasket in place.

    The extruded protruding side of the gasket goes towards, or faces, to compressor.

  • Massive leaks at both places where AC lines connect to compressor

    Hello,
    I'm working on a 2006 Dodge Caravan.

    For the 2nd day, I cannot stop leaks at the compressor underneath BOTH sides where the Oring and hose head fits into the compressor.

    On this vehicle there is a metal gasket that goes on the connection point. These gaskets are the ones pictured below.

    I've taken it all back apart three times now and the leak persists. I've done this procedure at least 100 times over the years.

    Any suggestions? Fatter Orings ?

    Can I leave the metal gasket out? I could swear I'm putting them in the same way they came out....flange facing compressor

    Time to replace the Brand New Dryer (AGAIN) ????
