Review on 4 Inch Malida Straight Coupling Fitting by Harald Patterson

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. However, I am a little disappointed that there are no clamps! The pressure side should be fine, but the pressure drop side may leak over time. 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.
