KUJOBUY hpbg-garden-water 1/2 Inch Venturi Fertilizer Mixer Injectors Agriculture Irrigation Tube^.

This worked great for my application. Note - i was just looking for a vacuum venturi and I did not use it as a fertilizer mixer.

Funciona bien.

This product does work, but not for my application. I have a veg garden with a drip system running at 10 psi thru drip tape. The flow is not adequate to operate the venturi, unfortunately. It works like it's supposed to in higher Gpm applications though. I had no problem using npt female adapters with the bsp threads. So my three star review is reflective of the description, nowhere can I find specs that would tell the consumer the limits of use, as far as Gpm and psi go. If you are going to sell this to American consumers, it's gpm and psi, not Barre and m3 and bsp threading. However, don't spend the money on a bsp to npt adapter. Theflon tape makes a good seal as is.

According to the specifications listed this should work with 200 GPH however one of the venturis I purchased does not work at all and it also wouldn’t work with up to 850 gph either. Now for comparison I made my own Venturi using 1/2” with a 3/8 core and 1/4” air tube and it blasts an impressive amount of bubbles. I will be demonstrating this product on YouTube in the near future and will show a side by side comparison how $2 in hardware is better apt for the task as a bubbler. I know someone mentioned it would draw air which it should however it cant even draw a liquid with a short 12” tube. Its pathetic really.

Can’t use it. Not sure what the seller thinks will fit. Waste of money
