INTRODUCTION
CORRECT METHOD FOR APPLYING FEMALE FITTINGS
To assure a reliable seal between female fittings and the adapters in this manual, it is necessary to observe
the following procedure, which differs from the one for assembling rigid pipes.
Female fittings without a gasket (metal/metal joint)
Screw on the nut by hand and then, with the aid of a wrench, tighten by another quarter turn.
Female fittings with O-ring
Screw on the nut by hand and then, with the aid of a wrench, tighten by another half turn.
In every case make sure that the pipe is properly aligned before tightening the nut on the adapter.
