1 42 BRASS W-INERLOCK JOIN BW Features Having resistance to high temperature, high pressure, and ultra low temperature. ightening torque is small, and no torsion is caused. Excellent resistance to a shock and vibration. No seizing is caused in the screw part of a nut. Can be used in the vacuum line. Superior in desorption repeatedly. Material he material of all of the main body, nut, and ferrule is brass. Applicable pipe Mainly pipe of the following copper stipulated by JIS H3300Oxygen-free copperc1020, ough pitch copperc1100, Phosphorous deoxidized copperc1201,c1220. Basic conditions of the applicable pipe O.D. Outside diameter O.D. olerance Surface hardness Surface condition Atmosphere for use Note 0.1 or less R V H R30-60 or lesshv120 or less here must not be harmful defects, such as roughness or wound. In principle, please use with liquid and the atmosphere that does not invade brass, the materials constituting a tting. Internal Structure Specifications/Pipe thickness and working pressure Operating temperature range Working pressureplease refer to the table below Pipe outside diameter Pipe thickness MPa Calculating conditions g Minimum tensile strength value of pipe206kgf/mm 2 Safety rate4 olerance of tube thickness0 emperature Please cut the pipe perpendicularly with the pipe cutter, and fully remove the flash from cutting perimeter. Moreover, please confirm visually that there are no wound or foreign substance etc. within 30mm from the pipe ends. When tightening the nut, please use the spanner suitable for the diameter of the nut hexagon. When changing the attachment angle of the fitting, please be sure to change the direction after loosening the nut of the fitting. Pressure-resistant strength depends on the pipe thickness. he above-mentioned numerical value is the recommended use value of the C1201 copper pipe. If the tightening work is difficult in the high or narrow plumbing space, do temporary tightening work, and be sure not to become the shortage of tightening.

2 Method of tightening Please insert the pipe, without removing a nut, into the fitting until the pipe tip hits the shoulder of the fitting inside. NotePlease cut the pipe perpendicularly, and be sure that flash is fully removed from cutting perimeter. Please tighten the nut by hand until it stops. Please consider this position as point and mark it. Please fix the main body of the fitting with a spanner well not to move. hen tighten the nut by another spanner at degrees written on the right. NotePlease do not turn the main body when tightening. NoteWhen connecting the plastic tube, please be sure to use the insert ring together. For connecting 412 plastic tube, please tighten 11/411/2 turns degrees. Method of re-tightening Please loosen and remove a nut after checking the position of a nut.he standard position of tightening. Please reconfirm that the front ferrule is equipped to the correct position. Before reconnecting, please confirm that the foreign substances are not adhering to the taper side, the front, or the rear part of the body. Please tighten the nut by hand after inserting until the front ferrule sticks to the taper sheet side of the body completely.when inserting, please be careful not to damage the taper part of the main body with the edge of pipe. hen, please slightly tighten the nut with a spanner from the standard position of tightening. Please see the right diagram. he cautions on plumbing Note When reconnecting the plastic tube, Please tighten 1/81/4 turn4590 degrees he standard position of tightening Re-tightening completion position ightened slightly more. ightening the pipe in the condition that the pipe end bumps the "tube stop part" of the main body of the tting is the foundation of W-INERLOCK JOIN. herefore the minimum straight pipe length Lis required. mm Pipe outside diameter Lmm LMinimum straight length of pipe Rmm RMinimum bending radius Other We are producing W-INERLOCK JOI under the severe quality control, but, if leakage etc. are generated by any chance, rst of all, please consult us. We will conrm it by tightening, and will investigate a cause with conrming the detailed situation of use, or the tightening state, etc. 43
