Body classTorque (N⋅m)
21.5 to 2.0
33.0 to 3.5
47.5 to 9.0

2. 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 appropriate tightening torques for piping shown to the left.
