Check Valve


This item did not work for me. It caused a major leak on my floor. I would not recommend. It deserves no stars but I couldn't submit without putting a rating, so I chose half a star.

Check valve


I did not care for this check valve. After receiving it, saw the poor quality did not even use it



Works great for me! I haven't had any problems from it.

Don't believe the others


This check valve works fine for me. I have had no problems with it thus far. I would really recommend it to anyone who needs a check valve. It is well made and easy to install.

A critical part of any aquarium


Especially for the price, these check valves are great and every air tube that goes into the aquarium should have a check valve.

Customer Review


it worked until I decided to use on another piece of tubing. As soon as I try to disconnect the it came apart.

It is very cheap garbage.


This is not worth the cadboard packaging it is in. Do yourself a favor and look at diffrent ones.
