(*) 1. PFA tube is used in the measurement.
2. General tolerance of tube is absorbed if the nut is tightened by the above torque value.
3. Number of revolution is begun to count up when tightening becomes fixed suddenly after lightly tightened by hand.
■ Features
Excellent in chemical resistance.
Possible to tighten the nut with a spanner without using special tools.
