    YSCB unit keeps breaking oil lines at the manifold. This is the 3rd one this summer. We finally got the new manifold in today that is billet aluminum to replace the original. This compressor doesn't seem to vibrate enough to do it. But it always seems to do it when we are covered up with work, And if you have ever replaced one you know what I am talking about.

    recovering 840lbs. r-22 10-12hours
    cleaning up oil all over the boiler room floor 1 hr.
    replacing the oil line 5 minutes.
    recharging the 840lbs. r22 10-12 hrs.
    job finished PRICELESS!!!


    Frick screw s3 or s5 series any help would absolutely delight me. thanks.

    Sounds like there is harmonics causing a problem, possibly?
    I've seen this happen on other systems.

    I question the term "Breaking".....
    If this line breaks, and no-one is there quickly, you will not be recovering any 840# of Ref....
    Methinks that the term "Cracking" would be more truthfull in this case...
    Secondly, Was the line replaced or just "patched" @ the joint???
    And Lastly....on any copper joint Silphosed, in particular one being patched that has already "Embrittled", it is "Imperative that an "Oxidizing" flame be used to reduce the "Carbonizing" of the copper being heated which will surely cause "Embritllment" of the copper joint involved, resulting in possible cracking & breaking as time goes on.
    As a side note, Since the entire ref. charge can be transferred to the condenser & stored to repair this problem, I have seen this problem corrected in less than 2 hrs....by Bubba himself no less..

    you are right they are not breaking in half they have always cracked at the ferrel on the compression fitting.

    Has stainless steel hoses been used successfrully in the field and rated for 250psi?

    Oh, and no we have never repaired a broken line. We have always replaced with oem parts.

    As both Carrene & Madhat posed;
    It does seem to be a Harmonic problem in that it appears that the piping arrangement does not like the 93 discharge pulses/sec and the lines seem to "buzz" with vibration.
    The hoses listed be madhat work great also...Pricey, but worth every penny.

    Is the flare a double flare? Need to use double flares on all oil lines. Don't assume it was done right, just because it's an OEM part.
