Solid build quality. Very heavy. Bought this to restrict the concentrate flow rate coming off of my reverse osmosis setup. This product page shows dimensions and choice of 6 mm or 10 mm orifice, which is excellent!Purchased the 10 mm 1/2" NPT to ensure full flow in my RO setup without any added restriction from the needle valve itself. Much better unit than my first purchase which had a tiny 4 mm orifice despite 3/8" connections.
