Review on 4 Inch Malida Straight Coupling Fitting by Brandon Gaines

For the summer heat we made a spray line and added a number of these valves to the lines. However, each of them eventually gave up the running water and licked everywhere. It seems like the small metal protrusions aren't gripping the plumbing lines very firmly and the water pressure is pushing the plumbing line out of the inlets. I had to apply tape (just a tiny bit halfway down the water line before inserting it to help the valve grab and hold the line. Not great but it worked in a pinch.
