Subject: Defect potentially reportable under 10CFR21

We are writing fLirther to our preliminary notification on October 6. 1999 about a possible defect in a Swagelok tube fitting part number SS-400-3-4TTM, male branch tee.

The utilities to whom we have sold this are repeated in the appendix to this letter. As we reported earlier the defect is a crack in the seat of the Fitting. This crack resulted front overheating during the resistive type heated forging process; it was not a defect in the raw material The estimated per cent of forgings that have this condition is less than 0.03%.

This forging was processed in December of 1996. Since the middle of 199~ we have required liquid penetrant testing on all resistive type heated forgings.

If there are any ~uestions, please do not hesitate to contact us.
