Notes For Tubing
1. Use the dedicated tool for connecting tubes. (See figure below)
Notes For Tubing - Reference Diagram
2. Tighten the nut as far as the end surface of the main body. In order to confirm that it has properly reached the end surface of the main body, tighten by a further 1/8th (approx.) of a turn. You will know that you have sufficiently tightened the nut if it will turn no further past this point. Be sure to also refer to the appropriate tightening torques shown in the table below.
| Body size | Torque (N·m) |
|---|---|
| 2 | 0.3 to 0.4 |
| 3 | 0.8 to 1.0 |
| 4 | 1.0 to 1.2 |
| 5 | 2.5 to 3.0 |
| 6 | 5.5 to 6.0 |
Note: For body size 1, tighten by hand.
