Subject:

SS-400-3 Heat Code EBY

Dear Valued Customer:

We are writing in regards to the twagelok Union Tee, part number SS-400-3. Our records show that yoe may-have purchaced some of thesc parts with the Heat Code #EBY.

A defect in the raw material that was undetectable has been discovered when the fitting was assembled for service. -The defect causes the fitting body to fail immediately upon pulling up the nut 1-1/4 turne The 20* flare of the fitting body splits longitudinally and will leak during system pressurization tests. When the nut is removed, the crack is very visible.

i Unfortunately some of these parts were shipped to.our customers before the defect was discovered. Fe have recalled i all of'our world wide inventories of this heat and out inspection indicates a_ defect rate of less than 0.1%.

Our experience indicates that the defect is found upon installation and/or testing of the system.

j If you have any unused inventory of the part number SS-400-3 Heat Code EBY, we would like to replace it.

Crawford Fitting Company e
