Metal Insert
The metal insert of our fittings is made of certified Italian brass, and it is featured by a special internal and external threating that has been designed to perfectly anchor to the plastic part and ensure therefore the maximum resistance against possible infiltrations and the maximum flexibility to both internal and external mechanical stress. Our Brass Insert has an internal coating, which does not allow liquids getting into contact with metal parts, in order to avoid corrosion processes and to ensure the long life of installations.
