Applications
Pressure feed of chemical liquids
Water trap
Fluid temperature control
Tube position can be changed according to the depth of the container.
Precautions
- 1. 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 is added to the tubing.
- 3. The nut should not be immersed in fluid during use.
- 4. Screw in the R or NPT screw after inserting the tubing. (If the screw is screwed in first, the tubing may become hard to insert.)
Precautions for piping
| Body size | Torque (N·m) |
|---|---|
| 1 | 0.7 to 0.9 |
| 2 | 1.6 to 1.8 |
| 3 | 3.2 to 3.5 |
| 4 | 5.0 to 5.3 |
| 5 | 10.0 to 10.5 |
| 6 | 22.5 to 23.0 |
1. As with the nut tightening, refer to the tightening torques to the left as a guide.
Tightening image
2. Tightening
After tightening the nut by hand, use the nut tightening wrench dedicated for 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 on left).
*See the manufacturer's catalog for product information other than that mentioned above.
