Jardin Plastic Aquarium Fish Tank One Way Air Check Valves, 2-Piece, Clear Black

These are cheap check valves. They seem to do the job so far but i wouldn't bet new carpet on it. Fair price for the product.

Seem to work fine and apparantly do not inerfere with air flow. We'll see if they work when the pump fails or a hose becomes detached. I am pleased.

I would definitely not recommend these check valves. I was looking for one to use in my CO2 injection system for my fishtank. The only options were $15 for a brass one or about $3 for two plastic ones, so I decided to try the cheap ones. After just the first night there was a fair amount of water that made it past the valve. They may work well for applications when there is gas (whether it be CO2 or just air from an air pump) going through the valve at all times, but if there will be times when there isn't, then I would look for something of better quality.

I gave it two stars because it IS cheap, so I sort of should have expected the outcome.
