Subject: Defects Potentially Reportable Under 10CFR21


We are writing to inform you about a possible machining defect in certain

stainless steel Swagelok tube fitting bodies.

A list containing the part number and the U.S.  nuclear facilities to

which the parts have been sold is enclosed.  All of these facilities have

already been notified by us about this possible problem.  It is only the

body of the fitting on an SS-1210-7-8 with the heat code HVM that is

involved; the nut or ferrules are not affected.

The possible defect is an oversized bore on the body of the Swagelok tube

fitting.  A machining operation on the bore of this product was allowing

cutting chips to sometimes accumulate on the tool, which caused it to cut

oversized on some of the parts.  The rate of incidence on the parts we

have inspected from these orders is about 0.03%.  Steps have been taken

to remove cutting chips from accumulating on the tool.

We have also increased our sampling inspection size on this product.

A sales drawing for the referenced part number is included with this


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