Notes For Tubing
1. The dedicated tool must be used for connecting tubes.

Dedicated tool figure
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. Refer to the appropriate tightening torques detailed below.
| 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 |
- *Be sure to read the notes before use.
