The radiator connection unit is used in two-pipe heating systems with stopcocks to connect radiators with bottom connections with a distance of 50 mm between their centers.
It allows the user to control the flow of the coolant and, if necessary, completely disconnect the radiator from the heating system. It is convenient to use with concealed piping to the radiator at the bottom. It allows you to avoid hidden connections of pipelines and increase the reliability of the system. The knot is connected to the radiator by threaded connection with self-sealing seat or with self-sealing adapter. This design provides a detachable leak-tight connection between the unit and the radiator without the use of additional sealing materials.
With the straight knot, the valve outlets for the connection to the pipe and to the radiator are on the same axis.
