Fluval Flex/EVOXII/Spec XV Nozzle Set – Directional Flow Outlet for Improved Water Circulation – Compatible with 9-16 Gal Fluval Aquariums

Fit perfect, appears to be same that oriignally came with my flex but i misplaced the oem nozzle after replacing with a low flow one and needed to switch back.

Works well, got for a pre loved fish pond that was missing it and allows the water to stay in the tank now

This must be my fifth spray nozzle purchased to try to improve the functionality of my Fluval Flex 15. I have Betta fish, and was trying to find a nozzle that did not create too much current. The problem is that when you get nozzles like that it’s very difficult to clean them. So I returned to the original item, and it turns out to be the ideal nozzle for this tank. It can be cleaned easily, and you can direct the current n ways so that it won’t affect fish that don’t like high flow. It’s made well, it’s durable and functional.

I attached it to the filter pump. It fit, functions as intended, no leaks, not broken.

Excelente calidad

This is the perfect replacement for my tank's pump connector.

Item was very small for what I needed it for but nonetheless was of great quality. Had to return due to item being too small for my output

I saw the price on this thing and wondered if I could use it for my return line with my Cobalt EXT Canister filter. The barb attached to this nozzle is a 1/2" female threaded to probably 1/2" barb. Now, my 5/8" ID is pretty thick (came with Cobalt Filter) and it fit snug, plus it's inside the tank so I don't really mind if any water leaks out. You can definitely get a different sized threaded female barb but keep in mind this thing is small, like it fits in the palm of my hand and the output nozzles are small and the opening slant is narrow. For my needs this worked perfectly because I wanted a more controlled water flow for my little fishies. overall, this is a good nozzle set to buy if you know what you need it for or would use it for!
