CESFONJERRO Water Systems Connector, OD Quick 1/4" quick connector, Push In to Connect Water Tube Fitting Set Pack of 20(Y+T+I+L Type Combo + Ball Valve)

Well priced. They were easy to connect to rainbird 1/4 PE tubing (which is fairly rigid, and completely fails with barbed connectors). The blue rings (to prevent the insertion ring from moving in enough to release the tubing) are flat. This makes it harder than other products that have a small tab to grip. But that also makes it less likely the blue ring will get pulled, so it's a wash.

Some parts do not fit, some do not allow water to flow, most leak water.

These were super easy to use when connecting swamp cooler water lines and no leaks.

Wanted to use it to add a line to my coffee maker but the T, the on/off valve and the angle connector all leaked everywhere. Tried different tubing and copper line and all leaked. Returning.

Value for the money

Nice assortment - great price

Well made fittings and nice assortment

Very easy to use, no leaks, makes quick work of tubing connections and reasonably priced.
