🐠 AKOAK 10 Pack Blue Plastic Fish Tank Air Pump Control Valves Aquarium Hose Connector - 2-Way Adjustment Valves for Aquatic Accessories and Supplies Review

Lots of air valves at a good price. The valves work great and I will actually be replacing all my existing fittings with these new ones.

These little valves were just what we needed. They arrived on time and well packaged. We use them in lab applications and they work well. Many Thanks

More than two days of delivery and no packaging. I doubt it's the seller's fault, but I still have to manually stir the water in my aquarium because I don't have air valves.

doing nothing, your fish will love you more if you create the perfect conditions. Maybe they are used for other purposes, but for aquariums you need as many of them as you have wood.

Product works fine as I use it. I actually use this in a homemade drip irrigation system. Love the fact that you can adjust the flow with a simple twist of a knob. I also love that you can get a lot of these for a very low price. I will buy again!

I bought them for a DIY brine shrimp hatchery. So I turned them off and back on twice a day. A few of these held up well but I'm glad I bought a large pack of these as they won't unscrew after a few weeks of use. Had to change them often

Cheap plastic control valve for air pumps. They work decently when not in use to constantly adjust airflow. If you use it as a set and forget, there is no problem. Because of the cheap material these valves are made of, they tend to tip over easily. Pros: - Very cheap - Works as advertised if not constantly adjusted. Cons: - Cheap - Easily flips plastic threads.
