Neck size
Neck sizes such as 24/410 give the thread diameter in millimetres and the thread style. The pump closure must match both numbers to seal properly.
Dip tube length
The dip tube should reach the bottom of the bottle so the pump can dispense almost all of the product. Tubes are often cut slightly longer and angled so they sit in the lowest corner.
Send a sample bottle
The most reliable way to get the right fit is to send your bottle or its drawing. We cut the dip tube to length and test the fit before production.
