   Do NEOPERL aerator part numbers have a meaning?
Part-number-small.jpg NEOPERL complete part numbers (as they appear on order confirmations) are composed of eleven digits and letters (alpha-numerical code: Bx.abcd.1.efgh).

The last 4 digits identify the washer, marking and packaging.

The first 7 digits (used in product literature or on the web) provide enough identification to determine the insert type, size and flow rate and the housing type, finish and thread connections:
