1 way valve works great!
Works great to seal off airbed pump tubing on double mattress, queen size completely!

Intended for a bit higher pressure than what i needed
These valves take a bit of pressure to open. they were not as sensitive to opening pressure as i needed. but they are quality pieces.

Junk- Do Not Buy
Absolute junk. Don't waste your time or money. First one I used worked for 2 hours then started dribbling. I tapped it a few times and it worked for a few more minutes. Swapped it with the second one, started dribbling right away. No Good

good quality. Works great
work great for dehumidifier pumping to drain. Keeps water from back feeding

They're ok
These work for the purpose of preventing back flow. They are however extremely difficult to insert even with a heat gun. And they tend to prevent forward flow just as much as back flow if you don't have amazing pressure.

Great value
Nice super small check valve, perfect for what I needed it for.
