“Works well, consistantly”
5.0

I was using a brass check valve on my calcium reactor's CO2 tank, but it corroded as everyone knows it will. This valve lasts, and won't corrode because it's plastic. That doesn't mean it's flimsy though - it's built tough and seems to be very well made. (I bought two... just in case..)

“Does the job”
5.0

I would get this over the brass check valve. my brass stopped working so I ordred this one which seems very good. Plus, this one came with instructions whereas the brass one did not. Plus, it costs less.

“Check Valve Upgrade”
5.0

I bought this valve to replace the cracked check valve on my calcium reactor. I like the positive tube locking nuts and the sturdiness of the valve.
