11 Safety Precautions (Supply Joints) The following is a safety precaution to Supply Joints. For other safety precautions, be sure to read the precautions on p.49. Warning With the exception of the Quick Fittings Rotary Type, do not use any quick fittings in locations where thread portions or tubes are subject to swing or rotations. The swing or rotations could result in damage to the fitting body. Use brackets or other support fixtures when subjecting the supply joint to bending loads or connecting supply joints in large numbers. Failure to use such supports could result in deformation of units attached to the supply joint or in damage to the fitting body. Caution For mounting or removing the Supply Joints, use the wrench provided for main block assembly. Without using this wrench could prevent easy assembly, or result in deformation of the main body. andling Instructions and Precautions Mounting Precautions for mounting the body 1. To mount the body, use a suitable tool to tighten it to the outer or inner hexagonal section of the fitting. 2. When tightening screws, tighten to the recommended tightening torque shown in the table below. Tightening to more than the recommended torque could result in broken threads or air leaks due to deformed gaskets. Tightening to less than the recommended torque could lead to loose screws or air leaks. 3. For fittings with fixed piping direction, tighten to the desired piping direction, and then adjust so that it falls within the range of the body tightening torque. Recommended tightening torque, sealant color, and gasket material Precautions for disconnecting the body 1. To disconnect the body, use a suitable tool to loosen it from the outer or inner hexagonal section of the body. 2. Clean off the sealant coating on the thread of the removed mating part. The coated sealant could enter other relating parts, and cause breakdowns. Method for tightening threads For tightening threads, use a wrench on outer hexagonal section. Tightening the outer hexagonal section Thread type Metric thread Taper pipe thread Thread size M30.5 M50.8 M61 M81 M121 M141 M181 R1/8 R1/4 R3/8 R1/2 Tightening torque Sealant color Gasket material 0.7N m [6.2in lbf] N m [ in lbf] N m [ in lbf] 5.98N m [52.9in lbf] 21.1N m [187in lbf] 34.3N m [304in lbf] 74.5N m [659in lbf] 79N m [6280in lbf] 1214N m [106124in lbf] 2224N m [195212in lbf] 2830N m [248266in lbf] White SUS304 NR Synthetic rubber (NR) Caution: While the quick fitting sealant can be reused a number of times, the thread on the mating part may also be adhered with sealant. Always clean out the inside of the equipment s female thread. Tube connection and disconnection Precautions for connecting the tube 1. Check that the cut section of the tube has been cut at straight angle, that the outer surface of the tube is not scratched, and that the tube has not become oval shaped. 2. When connecting a tube, failure to insert the tube all the way to the end could result in air leaks. Tube end 3. After connection, pull the tube to check that it will not disconnect. Precautions for disconnecting the tube 1. efore disconnecting a tube, check that the pressure inside the tube is down to zero. 2. Push the release ring evenly all the way to the end, and then pull the tube out. An insufficient push could make it impossible to pull the tube out, or could scratch the tube, leaving scratched tube material inside the fitting. 380

12 andling Instructions and Precautions Tube connection and disconnection method 1. Tube connection The fitting type in the main block (quick fittings) is equipped with a lock claw that holds the tube in place when it has been pushed all the way to the end, and with an elastic sleeve for sealing the tube periphery. d 2. Tube disconnection To disconnect the tube, first push on the release ring, releasing the lock claw, and then pull the tube out. Always stop the air supply before removing the tube. c d For cases where tight or cramped piping spaces hinder tube removal operations, a special tool is available. Consult us for details. Special tool for tube removal For 3 [0.118in.], 4 [0.157in.] and 6 [0.236in.] tubes Order code : UJ-1 For 6 [0.236in.], 8 [0.315in.], 10 [0.394in.] and 12 [0.472in.] tubes Order code : UJ-2 Usable tubes Either nylon or urethane tubes can be used. The tube outer diameter accuracy should be, for nylon tubes, within 0.1mm [0.004in.] of the nominal dimensions, and for urethane tubes, within 0.15mm [0.006in.] of the nominal dimensions, while the ovalness (difference between long diameter and short diameter) should be within 0.2 mm [0.008in.]. Cautions: 1. Use tubes with no visible scratches on the outer surface. If a scratch is made during repeated use, cut off the scratched portion. Cautions: 2. Do not bend or twist the tube too much near the connection to the fitting. It could result in air leaks. The minimum bending radius for nylon tubes is as shown in the table below. mm [in.] Tube size 4 [0.157] 6 [0.236] 8 [0.315] 10 [0.394] 12 [0.472] 16 [0.630] Minimum bending radius 20 [0.8] 30 [1.2] 50 [2.0] 80 [3.2] 150 [5.9] 500 [20] 381
