Defects Potentially Reportable Under 10CFR21 We are writing to inform you about a possible'machining defect in certain one inch stainless steel Swagelok front ferrules, part number SS-1 613-1.The front ferrule is shipped as a component in a Swagelok tube fitting, or sold separately as a replacement part.A list containing the part numbers of assembled fittings and nuclear safety related certifications under which these ferrules have been sold is enclosed.All of these customers have already been notified by us about this possible problem.Only front ferrules with the heat codes ILA, JVA and JYL stamped on the part are affected;and only one inch ferrules are involved.The possible defect is that the 45 degree chamfer on the trailing edge of the ferrule may not be correct.A drawing is enclosed that shows this dimension, along with a drawing that illustrates the front ferrules'osition in the Swagelok tube fitting.When these ferrules were machined, an improper set-up allowed a few pieces to be manufactured with an inappropriate dimension.

Our inspection of the lots involved shows that about 0.019 per cent of the ferrules manufactured in these lots were affected.Laboratory testing of these parts with this incorrect dimension had the tubing slip out of the fitting at three times working pressure of the tubing.Our corrective action includes doubling our sample size on these parts and implementing a long term project to 100 per cent inspect using automation.

If there are any questions, please do not hesitate to contact us.Sincerely, 3 A"lflid 98093.50ibb 980909 PDR ADOCK 05000250 8 PDR en n J.Malec ice President&General Manager Telephone:
