NIST outlets are those points, fixed or flying, of a medical gas distribution system on which the user makes frequent connections and detachments to take the different gases intended to power the anesthesia, ventilation, and medical use equipment in general. Because an incorrect connection can endanger the patient’s life, it is important that the terminal units and their components are safely installed. Materials used: body chrome CW614N brass and other details, C98 steel for springs, NBR rubber or VITON food for seals, polycarbonate for labels and copper for the outgoing pipe.
