First, measure the length of the double-ended hose, and weave the hose (stainless steel, aluminum wire, stainless steel bellows, white leather tube, aluminum wire outer hose, etc.). ) About 28CM is 38CM, and so on. After measuring, cut it with a steel knife. After cutting, put stainless steel leather caps on both sides, and then put the hexagonal cap and copper core (with iron core and aluminum core) into the braided tube, so that the hose is formed, but it is not good. Furthermore, adjust the tightness of the embossing die of the extruder, and put one end before embossing (embossing is the stainless steel leather cap at the joint between the hexagonal cap on the hose and the braided tube). If the copper core is too loose and too tight, the embossing die needs to be readjusted. If this happens, put the other end into it for embossing. This way, the hose is fine, just need to be packed. Pointed hoses (single-hole hot and cold water hoses) are 40CM and 50CM. It's hard to say, and the pipe is cut entirely by the length of the tines. There are 28 cusps, 32 cusps, 38 cusps, 42 cusps ... 100 cusps ... others are the same as above.
