Ziss Premium Air Valve

The Ziss Premium air valve is made to a high standard than any other valve on the market. I have since been switching out every air valve I use for thse. These control the flow of air from an air pump. Very useful in small tanks or larger tanks where you want to split air.

Good Build, but Not Fully Functional

I needed inline air valves to adjust down the flow from the pump to the air stone on two different tanks where more O2 is probably necessary, but not nearly at full blast. I came on here to buy the little green plastic ones I've always purchased in the past. Well, they're no longer on here, but this looked better for the price.

The construction build is definitely way better, but the valve does not function correctly. The knob is very tight, and it doesn't close all the way. Not a big deal if all I'm doing is making the bubbles chill, but what if I want to turn it off? I do that a lot of times when I'm feeding my beta since he's kind of stupid and can't seem to smell the food to go after, so I don't want it floating away from him quickly. I did buy a third valve for that tank, but I ended up leaving the green plastic one inline since it does shut all the way off.

I see that someone said they used plumber's tape to fix a leak (maybe the same issue), but hell if I know how to do that. I'll have to try. As is, it's a 2. If it shut off all the way and was easier to turn, it'd be a 5.

Best air valve!

After using numerous air valves on my central loop air system this has been the easiest to adjust and the most durable. Solid construction, and finally an air valve with a large adjustment knob that is easy to fine tune.


It is an air valve. It does what it is suppose to do. No complains.

They are ok.

They all leak past the adjustment screen. No real big deal. Just used a little plumber's tape and stopped the leak.

Works great, shipped fast!

These work great. I bought these to replace one that stopped working (different brand) on my sponge filter line. Keeping extra of these on hand in case I want to add lines or replace old valves.

Live Arrival Guarantee
We guarantee our live products will arrive alive. We ask that you do your part and minimize the amount of time our packages sit out in the elements. It can also be a good idea to avoid ordering live items during extreme temperatures. This would be when night time temps are below 35 and over 80 degrees during the day. Now these temps are not for sure death, it's just what makes it easiest for all of us during shipping.

When temperatures are cold we will use heat packs and extreme cold styrofoam liners. Shipping live goods is difficult as our warehouse could be 70 degrees and your home could be snowing, and all the stops in between. We do our best and will make it right for you and may request to try again at a different time.  During heat waves, it's best to avoid ordering live goods as ice packs etc don't do enough to mitigate it.
