Great quality check valves
Great quality check valves for a really reasonable price. Not much to these. Worked great for fixing my Keurig 2.0 K200 coffee maker which had a damaged air pump (very common problem I learned). Replaced the air pump and tested operation. Worked great but noticed water was being pushed into it, which is what caused it to fail the first time. Added one of these check valves in line and life is great now. Shame on Keurig for planned obsolescence.

Best valves available.
Here is an honest review from a verified purchase. I have been keeping aquariums for 40 years. These are among the best valves I’ve had. They work perfectly. Any review that says otherwise was written by someone that doesn’t know what they are doing or they were using them wrong. Simply slide a paper clip or toothpick into the opening and gently open the valve before connecting. After all you want a good seal to avoid water back flow. The air has air flows beautifully. They are easy to connect using some warm water on the tubing. They have nubs to keep the hose on. These are great valves. Don’t pay attention to negative reviews.

Works effectively but the hoses slip off over time.
The airflow control works just fine but due to the smooth tapered connectors, the hoses constantly slide off. I had to superglue the hose onto it

Exactly what I needed
Thank gosh for these! No more water going back to the air pump when power goes out. Have been using one for a long while now with no issues. Super easy to install, no extra noise, exact fit, and does what it should. I own a 75 gallon fresh water tank.

Air restriction
4 of them worked fine the other 2 had way more resistance it slowed down the air flow a lot

Reliable Check Valve for CO2 Blow-Off and Suck-Back Prevention
This check valve has been a solid addition to my homebrewing setup! It works exactly as intended—preventing suck-back during cold crashes and stopping CO2 blow-off from backflowing. Easy to install and gives peace of mind during fermentation. A simple but essential piece of equipment for any serious homebrewer. Highly recommend!

One out of six supplied leaked and admitted air.
Work well for water as well as air. The halves of the body screw together, and one of the six supplied admitted air through the join. A bit of solvent glue on the threads fixed that.
