They are both two-piece, flat housing nozzles with brass interiors and nickel-plated copper exteriors. Cutting thickness is marked directly on the nozzle and are indicative.
Nozzles should be selected based on cutting thickness and on the gas to be used. AC nozzles are to be used with acetylene, while NX nozzles are used for cutting with propane.
All lances are APRAGAZ approved and have been tested individually in operating pressure with a lit flame.
All constructive components are also separately marked to ensure greater safety during coupling.
