Ziss Premium Air Valve

The best air valve no doubt. It holds solid and doesn’t slip. Love them. Quality is head and shoulders above others.

This is the best air valve I’ve found. The cheaper ones don’t hold position and slip, changing the flow. It was maddening. This one is well- made and does exactly what it’s supposed to.

I use this to lower the air pressure going into my fry tanks and it works great!

I have an air pump that had no air control valve, so one day I jumped on yahoo videos and came across Aquarium Co-op and watched Corey gave a video demo on this item and I was sold. I purchased it and from the initial order to the delivery I had no problems. I attached the valve to my air line, which I use to operate another item I bought from ACO, a sponge filter, which is a fantastic filter that has my water looking crystal clear. I can adjust the air flow by using the valve. This is a great product and I highly recommend buying it for your tank.
