| Title | Part 21 Notification - Fisher Type 67C Series Regulator Screw Fracture |
| Event Description | The manufacturer provided the following information via facsimile:
This is a summary of a communication that was sent to inform all Fisher customers of record. Fisher Controls has determined that a faulty batch of screws (Fisher Part Number T13526T0012) was used in the applicable constructions listed below. In some cases, a fracture occurred in the threaded shank, while in other cases the screw head fractured. Multiple screw fractures were also found on the same regulator. The screw fractures were found in four different product orders. The function of the screw depends on the type of construction:
If the screw is compromised, the ability of the regulator to retain pressure or function correctly may be impaired. Any abnormal function of an instrument supply regulator might, in turn, cause unexpected behavior of the instrument itself due to supply pressure changes. These changes could result in a range of performance problems, up to a loss of process control. Fisher has stopped shipment of these products and is currently purging their inventory. This notice applies only to the subject equipment supplied by Fisher Controls International LLC that meets all of the following criteria:
