It is a sprinkling nozzle made by Gilmour. I used domestic products frequently, but it is even heavier than those and it seems to be used for tough. The fragile lever also uses a thick plate. A water column with a diameter of 6 millimeters extends more than 1 meter! I admire accuracy. As an improvement point, there are also small types which are one size smaller, so it would be nice to buy it as well. Also, since the size of 3 / 4inch - 11.5 (ASH) is slightly different from G3 / 4, pitch should not match with the screw mouthpiece such as the headliner. Although the parts of the 100 water spray nozzle on hand are used miraculously. [BSP screw] I decided to order Japanese screw conversion converter.
