We purchased Robinia acetylene burner from screw type for use with one touch coupler. The last purchase purchased this time because the packing in the middle swelled in about 3 years. Well it is a consumable item.
I knew the coupler set (8000 yen) for the domestic hose of the hurricane burner but I used one adapter on the banner side and made a domestic hose using a domestic AS pressure reducing valve as a coupler. After all, domestic hose is thicker and handling is bad, but it is safe. Moreover, it was saved at less than 2,000 yen in 2 cases at a low price.
