What is the thread size of the drain valve (tap) on an ultrasonic cleaner?

All of our ultrasonic tanks that are 6 Ltr capacity and larger, have a drainage tap for emptying the fluid.
FYI: 3 Ltr tanks and smaller do not have a drain valve.
The thread size on DK Sonic & GT Sonic ultrasonic tanks is: 1/2" BSP (half inch BSP). Buy a replacement drain valve HERE>>>
