These are the quick releases we use. They’re the highest quality ones I could find. Happy with them for two years of use so far. An occasional spritz of silicone if they ever get sticky then they’re buttery smooth again. All the quick releases mean everything goes together quickly and easily, with the only threading required at the spigot.
How did you attach the cap to city water inlet to seal the quick connect when not in use?
The end result protrudes a couple of inches, but so what. During inlet use the female QR and male plastic plug never come apart but just dangle on the cord. Photo shows them apart just for demonstration.
