Simple and easy it works
The title says it all. I have them installed on all my air lines. Check valves are very cheap insurance for my air pumps.
Having these on each of my hoses is Peace of mind
Works well always a good idea to have around if you use sponge filters.
Ordered 3, got 3. All worked. No muss, no fuss. It's a check valve. It does a job. It doesn't complain. Buy some.
