    Working on a existing lobster tanl in a resturant,the copper to plastic tubing joint keeps leaking,I repaced the
    3/8" compression joint, but it still leaks. Any one have any good ideas? The unit is using "hot shot"

    3/8 compression

    Did you put the metal sleeve inside the plastic tubing for support?

    I didn't think you could use compression fittings of refreigeration.

    lobster tanks

    The compression fitting was "factory" but it leaks there, I replaced the compression fitting with a new one,and can't get a good leak proof joint,it is tough getting the farrel over the plastic I think it may have swelled with time. They use a plastic evaporator coil in the water because lobsters can't stand any exposure to copper it kills them.

    If using an insert doesn't help I'm of no help here. Only seen 1 tank in my life.

    I tried that, but it didn't work and the plastic tubing appears to have swollen with age, I see no manufacture's tag, I'd like to see if i could get a new evaporator or see they might have a fix, it must happen elsewhere at times.

    I ran Into the same problem about a year ago. i replaced the tubing, nut and ferule with air brake tubing and fittings that you should be able to get at any good auto parts store. so far over a year and no leaks. let us know how you make out

    Comming out of left field is..

    If your tank has a water pump system go get a water condenser, reverce it, and put a TXV.

    If your system has been serviced, with hot shot, you could has some acid in your system that will melt the plastic evap.

    Create a chiller for the tank, and you will be much happier.
