Precautions
- Use special tools to connect tubing.
- Tighten the nut until it touches the end surface of the body, and then tighten it an additional 1/8 turn to ensure that the nut has reached the end surface. If the nut will not turn any further, then it means a sufficient tightening has occurred. Refer to the proper tightening torques shown below.

|---|---|
| 1 | 0.7 to 0.9 |
| 2 | 1.6 to 1.8 |
