This 40mm Tank Mozzie Screen allows water to pass through the overflow while blocking entry for mosquitoes and other insects. It can also be connected to the outside of the tank inlet (if not connected to a pipe supply), or alternatively the inside of the tank inlet.
Note: if you want to fit this accessory to the inside of your inlet, and you bought a JoJo water tank prior to the year 2020, you will need to purchase our Full Thread 50/40mm Reducer.
