These replacement dosing heads can be used to replace old or non-working dosing heads on the WiFi dosing pump. The new dosing pumps include spare heads, so you may want to consider that before ordering one.
These are the latest model of dosing heads, which come with upgraded tubing and heavier duty connectors for improved dosing reliability.
These will fit the WiFi Dosing pump (WF4)- they are not compatible with other models like the kamoer or DP-4.
