Types of use (Condition A)
Condition A
- For applications including boring through panels or walls, etc.
- Atmospheric release
There are presumably two different types of use for the bore through connector as indicated in conditions A and B, and the specifications will differ according to the type of use.

Use under condition A

Operating range for the bore through connector
Types of use (Condition B)
Condition B
- For applications where sustained pressure is applied to the internal thread
- Using the same pressure and temperature as that of the inside of the tube
There are presumably two different types of use for the bore through connector as indicated in conditions A and B, and the specifications will differ according to the type of use.

Use under condition B

Operating range for the bore through connector
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) |
|---|---|
| 2 | 1.6 to 1.8 |
| 3 | 3.2 to 3.5 |
| 4 | 5.0 to 5.3 |
1. As with the nut tightening, refer to the tightening torques to the left as a guide.

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.
