Defects Potentially Reportable under 10CFR part 21 We are writing about a potential defect in a Swagelok stainless steel front ferrule, part number SS-503-1.The part is marked with the heat code IVD on it.The front ferrule is shipped as a component in a Swagelok tube fitting, or sold as a replacement part.The list of utilities to whom we have sold these parts is enclosed.We are notifying each licensee concurrently with this notice.The potential problem is that the ferrule was machined with an improper length, resulting in the 45 degree chamfer at the trailing edge to be missing.Laboratory testing of this part has shown that it will leak immediately on gas service, and will hold to about 2.5 times working pressure of the tubing during a hydraulic pressure test.The improper length was caused by insufficient feedout of the bar on a multiple spindle machine.Our analysis shows that this would be a first part error and that only a small number of ferrules are affected.Our automated assembly equipment is set to reject this condition, and of the parts that were not sent through automated assembly, about one per cent of the lot is included.Corrective action includes inspection equipment that will 100 per cent identify this short length.A sales drawing that shows a proper ferrule and one with the short length is enclosed.If there are any questions, please do not hesitate to contact us.98i0280iiO 98iOi9'oo ADQCt4', OSOaOSSS S" PDR W<I i Sincerely en an J.Malec Vice President and General Manager Telephone:
