For what? If you use a moonshine still with a flowing refrigerator or dephlegmator, you will need an adapter for a mixer to connect a hose with a diameter of 8 or 10.5 millimeters. For reliable installation of the tube on the fitting, conical machining is made to ensure tight contact. The adapter is equipped with a water pressure regulator, by changing the position of which you will regulate the efficiency of the cooling element.
Material. Stainless steel is corrosion-resistant, does not deform over time, so the adapter will last a long time. Moonshine machines made in Russia
