The operating pressure or operating temperature range for each tubing size differs depending on the usage conditions. Keep the supplied fluid pressure and temperature within the range of each specification. 2. The piping should be arranged in such a way that no extraction force other than the fluid pressure should be added to the tubing. 3. Avoid using in instances where the nut is soaked in the fluid. 4. Screw in the R or NPT screw after inserting the tubing. (If the screw is screwed in first, the tubing may be hard to insert.) Note) For details of the applicable tubing sizes, refer to page 823.

Tightening After tightening the nut by hand, use the nut tightening wrench dedicated to the LQ1 to tighten the nut securely. The tightening is enough when the clearance between the end face of the nut and the body is 2 mm or less (Refer to figure 1). 2 mm or less Piping Tightening torque for piping Body size Torque (N.m) 0.7 to 0.9 1.6 to 1.8 3.2 to 3.5 5.0 to 5.3 10.0 to 10.5 22.5 to 23.0 1 2 3 4 5 6 1.
