・ L1 = 200-1500 mm
・ The mass shown is when L1 is 500mm of straight pipe. For the mass of DOVEA with a longer/shorter pipe, please add or subtract the corresponding mass (shown below) for each 100 mm of L1 length, according to Nozzle Thread Size 1. (When the Nozzle Thread Size 1 is 1/4F, mass per 100 mm is 63 g, when 3/8F it's 85 g., when 1/2F it's 130 g)
