I am currently using these check valves to protect the RO membrane from back pressure from my storage tank and to aid the shut off valve. The tubing fit perfectly into the check valves and locked into place providing a secure connection without leaks. I tested them and they worked fine allowing flow in one direction only and I removed and reinstalled them without any issues. I have not yet tried them with pressures above 50 psi, but am considering adding a booster pump so hopefully there will not be any problems at 80 psi.Make sure you install the check valves with the proper orientation. I like that they have a directional arrow right on the outside of each valve to help remind you.

I ordered the 5-Pack Push to Connect One Way Check Valve for Reverse Osmosis Water Filter to replace a bad check valve on my RO system. This was the second to go bad so I got a 5-pack in order to have spares.So-far-so good with this valve, it fit and worked perfectly...all at a great price!
