Did not work
These did not allow ANY air to pass through, in either direction. Could not use them.

Complete Trash
These are complete trash. Cracking pressure and pressure drop are way to high for aquarium pumps! Don't waste your time and money.

Valves are very hard to open
It takes over 2psi to open the valve in the forward direction. My aquarium air pump was not strong enough to push air through it. I had to use a tire pump with pressure gauge to figure out at what pressure it opens. A better alternative is Lee's aquarium check valve, opens at 0.8 psi, and has zero backflow leakage, you can even open it by blowing with your mouth
