24mm Black Gel Pump with Overcap

Overcap is clear

this pump will fit all standard 24410 bottles, but the dip tube is too short for our 250ml Tall Boston Bottles and our 200ml Aluminium bottles.

dispense rate is 0.55ml-0.65ml avg.

When screwing onto a glass bottle the skirt must be screwed tight - and must be screwed one more rotation once the wide part of the bottle neck is reached.  You will see a slight splaying of the bottom of the skirt as you force this last rotation.
