I got a new tap installed recently and I used to be able to screw in the grainfather hose barb directly to the tap. However this tap has a female thread meaning I can't screw in my barb anymore. does anyone know the name and measurements of the parts I need to buy? Alternatively, when buying a Grainfather does it come with a female to male converter? I lost a few of these small parts a long time ago. Thanks.
