I tested each check valves, at first only two worked, then re-tested the rest and all worked. These are tiny and uses 1/8 ID air hoses. Works well for aquarium air pumps, no so much for liquid use.Affordable and reasonably priced.

The valve itself is 3/4” only but the line connection is only 5/32 which is smaller than 1/8”, so if you have a line that’s 1/8”Internal diameter it would not hold tight without a clamp, sealant, or zip tie. Moreover the opening is such a tiny pinhole that it would really create a flow bottleneck. When I buy a 1/8” check valves I expect that at least the OD would be 1/8” and the ID would be at least 75% of that allow for good flow while maintaining some strength. Neither is the case here.
