To avoid leakage, pay attention to the following points:
1. Tighten the flare nuts using two wrenches. Pay atten-
tion not to damage the pipes.
2. If the tightening torque is not sufficient , there will
probably be some leakage. With excessive tightening
torque there will also be some leakage, as the flange
could be damaged.
3. The surest system consists in tightening the connecti-
on by using a fix wrench and a torque wrench as below:
