ST-73.1 Nipple (Black)

The black nipple for the ST-73 indicates that the foamer is set up with a 1.25mm nozzle. Nozzles must be selected and installed based on the specifications of the pressure cleaner being used.

Please note: the nipple serves as an easily visible indicator of the internal nozzle’s sizing and connects to the chemical pick up hose in the foamer.

See the Product Date tab below for the ST-73 nozzle sizing chart.
