I needed these for a toilet fill valve. Unfortunately, the flow stops when it's high pressure. It only works with low pressure applications.

Worked great when used with 7mm silicone tube. They might be a little stuck when you get them but I just blew through mine and it loosened them up. Blocks both air and water from flowing back. Great little check valve.
