nual, it is necessary to carry out the following procedure, which is different from the one for the assembly
of the rigid pipes.
Female connectors without gasket (metal/metal connection)
Screw the nut manually and then tigthen 1/4 turn by means of a spanner.
Female connectors with O-RING
Screw the nut manually and then tighten 1/4 turn by means of a spanner.
In any case make sure that the pipe is correctly aligned before tightening the nut to the adapter.
