YZM1/4" OD Check Valve Quick Connect Push In to Connect Water Tube Fitting (Check Valve)

Easy to use like any push fit plumbing fitting. Good value for this little fitting kit. Mark the insertion depth on the tube beforehand. Just to make sure you have a secure connection.

Good

Really wish they included clips to prevent them from backing out. Now I have to figure out how to secure these.

Liked the price

UPDATE: 10-18-18. I discovered the valves will not create a reliable shut off when using CO2. Found this out when I was force carbonating on keg at 40psi, and shutting the valve to my (already) carbonated kegs. The valves let a small amount of gas through, causing them to hold at 40psi as well. Do not rely on them for this purpose!Works just as good as the expensive brands. They include blue clips that prevent accidental removal. Not necessary for normal use.I used this set for a CO2 beer gas setup. Everything seems to seal up fine.

For my needs I needed to split and reconnect  General Electric WX08X10006G SmartConnect Water Line, 6-Foot Length  tubing to the same type used in my GE side by side model PSS26LGSBBB refrigerator. These are not the highest quality connectors out there, I'd grade them a solid B rather than an A, but the sheer value, the quantity and variety you get more than makes up for their slightly cheap feel.After placing a tube into any of the holes you must also place a (supplied) "C" ring around the blue plastic to keep the tube locked in place. It wasn't something I've needed to do before with similar quick connects but it was no big deal.

The clips are not included. Looked at reviews and I guess they stopped including them at some point. Such a hassle, have to rate down, but the fittings themselves seem fine.

Connectors seem fine, but I was supposed to receive 4 ball valves based on description and only received 3.
