4 Inch Malida Straight Coupling Fitting Review

The valves themselves work properly and smoothly. There's an internal cross brace that restricts flow by maybe 10%, so it's not a big deal.

The pressure holds them in place, and ALL other Malida 1/4" tube fittings I've ordered before came with tension clamps, so I'm a bit frustrated. Overall this is a good product and simplicity is its strong point.

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.

These small valves offer full flow and reliable shutoff. The fittings are reliable (do not leak) and very easy to install. The valve action is 90 degrees, from fully open to fully closed, with no leakage. I unreservedly recommend them to anyone who needs quality, reliability and economy in their drinking water service…
