R20 thread is a standard thread size that is used on many manifolds, including the Uponor Tru-Flo manifolds. It does not equate to any standard size (like 1/2" or 3/4"), but is its own unique size. Specific diameters of the holes are not listed, but these fittings are designed to fit with standard PEX-al-PEX sizes (5/8" fitting means it is compatible with 5/8" PEX-al-PEX).
R20 thread seems to be close enough to screw on 3/4 thread just fine. However, if you thought about using this one to connect a European panel radiator and use one of the isolation valves for it (SKU:7738317849 for example), this particular fitting would not seal tight on EK20 (Eurokonus) used on those. The the 0-ring is a tad smaller and does not go in as deeply. Uponor in Europe sells part number 1058090; however, it is probably not possible to find in the USA. I have not tried one of these yet: SKU:2410500. Maybe customer support will figure out the right fitting to use with Uponor MLC pipe and panel radiators. Good luck!
No, these are not NSF rated.
