Threaded Connection Markings

With the exception of the threaded PVDF antenna, threaded connection markings are
found on the flat face/faces of the process connection.
Serial number:a unique number allotted to each process connection, including the date of
manufacture (MMDDYY) followed by a number from 001 to 999, (indicating the sequential
unit produced).
