These are easy to use and fit well with my aquarium bubbler we have had no leaky connection points, so these are great for anybody needing to put backflow valves into their tanks

These haven’t given me any issues and I actually had a power outage recently and no water came out of my beta tank so I would say it did it’s job!

These little guys work well, I only needed one but the six-pack was so cheap, it's an inexpensive insurance policy

In all my decades of owning a fish tank I finally had a check valve go bad. These work great and are easy to install. Pay attention to flow direction it's molded into the clear plastic.

Excellent one-way check valve.. although not recommended, I've used these on an CO² tubing and they actually work better than some CO² C.V's I paid twice as much for.Would STRONGLY recommend for normal air pump lines on the aquarium.

Only needed one. Works the way you would expect. And it's nice having the extra laying around.

These work, but do not hold up to much stress. I’ve had two break in the air-hose nipple.I’ve stopped using these, still looking for a purge valve solution..

Works perfectly. I use it for my fish tanks and as a diy burp valve for my fermentation jars.It does not work for co2 systems unless you seal the junction between the 2 plastic pieces. I did seal it with some glue and is working perfectly on a co2 system for my planted aquarium.
