The elbow d20 × 1/2″ with a female thread is a fitting for the firm right-angle redirection of a 20 mm diameter pipe run with a transition to a 1/2 inch threaded connection.
The reinforced walls of the fitting withstand the mechanical stress that arises when changing the direction of the pipe, while also preventing deformation of the joint during installation with a tightening torque.
The combination of socket and thread is practical at points where different types of pipe systems meet or where threaded unions, pumps or fittings with a 1/2″ female thread need to be connected.
