Ziss Premium Air Valve

Easier to install than my old air valve and yet paradoxically has a tighter seal with the airline tubing. Also, the valve is much easier to adjust and more precise in air flow control. Very pleased!

Had to get this because my sponge filter was a bit too bubbly for my floaters, and works great! Very precise on the bubble amounts, just gotta be slow when adjusting.

I'm a rather new fish owner, and just installed the Ziss air valve I picked up at a shop recently. So far so good. I like how it isn't directional like the more standard one I was using, and is easy to adjust. Not sure yet how easy it will be to remove the tubing in the future, but it seems robust enough to take some abuse if the tubes need to be twisted off.

Works great! Great quality and control.

I am so used to the plastic cheap or the brass airline connections. These are excellent! It's the best of both worlds. Heavy duty yet light weight. Will get more as needed.

This product is solid. I use them on every air line I run in my fish room. Great control and amazing price.

This valve is probably the best I have found. And I've been involved in the aquarium hobby since about 1970. So that's saying a lot. Of course I haven't used every brand. But when you find one that you like there is no reason to look any further. The functionality is very well. Because the threads are fine threading they are easy to finely adjust. And there is no air flow restriction when fully open. The only problem, which is relative is that they are just a little hard to turn. But once they are set there is not really any reason to change them under most circumstances.

Most resistant and reliable valve you can get. Very versatile, great for air or water
