## Discrepancy

(CAN) DURING TROUBLESHOOTING A SLOW OXYGEN LEAK, IT WAS FOUND THAT FITTING, PN MS20822-5D THAT APPEARED TO BE LEAKING ON THE RT PILOTS O2 MASK STOW BOX.  ONCE REMOVED, UPON INSPECTION THE FITTING APPEARS TO HAVE SOME SORT OF MANUFACTURING DEFECT.  THE DEFECT DOES NOT APPEAR TO BE THE SOURCE OF THE LEAK, HOWEVER A NEW FITTING IS BEING PROCURED.
