Common Safety Instructions for Products Listed in This Manual
4. Cautions on the fitting of tube
(1) Make certain that the end of the tube is cut at right angles, the tube surface is free from flaws, and
the tube is not deformed into an ellipse.
(2) When fitting a tube, refer to the dimensional specification of Table 2. To prevent leaks, insert the tube
to end (C) completely.
(3) On completion of fitting, make certain that the tube does not come out at your pulling.
5. Cautions on the release of tube
(1) Before releasing the tube, make certain that the pressure inside the tube is zero.
(2) Push the release ring fully inside and pull out the tube. Unless you push it completely in, the tube
may not come out and scrapings of tube may be left inside the joint.

7. Cautions on the removal of joint body
(1) When removing the joint body, loosen it with a proper tool, using the outside or inside hexagon.
(2) Remove sealant sticking to the thread on the mating equipment. The sealant left sticking may enter
the peripheral equipment and cause trouble.
6. Cautions on the installation of joint body
(1) When installing the joint body, tighten it with a proper tool, using the outside or inside hexagon.
(2) In tightening the screw, use the tightening torque recommended in Table 2.
・ Use of a torque highter than the recommended level may damage thread or deform gasket, thus
causing leaks.
・ Use of a torque lower than the recommended level may cause loose screw and leakage.
(3) With the joint whose piping direction will not change after tightening, make adjustment within the
recommended range of tightening torques.
