The following torque values should be used for tightening CPV O-SEAL® Union Nuts when making up a joint.
The values apply to joints installed into a piping system. They do not apply for stock assembly or, for shipping assembly. In the latter case hand tight is acceptable.
The minimum values establish the lower limit for permanently made up joints. Torque values below the minimum may be used for temporary service. Torque values larger than the maximum are not recommended without consulting the CPV Manufacturing engineering department.
