Marking of Standard Lee Inserts

In order to provide complete traceability of our products, The Lee Company individually marks each standard insert, with the exception of Lee Plugs, with the appropriate twelve character part number and six digit lot number. For special products, additional information such as serial number, flow rate, etc., can be provided depending upon individual customer requirements. Examples of the standard marking are shown below for a typical restrictor insert, valve insert, and a restrictor installed in a union.
