The Original Black Sheet Packing The original Black Sheet and the most effective packing of the kind. Why? It is a scientific and at the same time a secret formula which our many competitors have endeavored to dis- cover by having N.B.O. analyzed and other- wise, but without success, with the result that N.B.O. is and always has been the absolute master of the field. Other N. B. O. Products N.B.O. Pump Valves made soft, medium and hard, for all high duty services. N. B. O. Steam Hose—With a tube of genuine N. B. O. stock that positively cannot harden up under any steam pressure. In use on the leading railroads of the country and in many other places where other makes.of Steam Hose have been tried and where none but the best will be considered. N. B. O. Tubular Gaskets—An article that is guaranteed to give you very superior service. N. B. O. Rings and Spiral—For refrigeration service. By many experiments and tests it has been proven that N. B. O. is the best ammonia resisting stock made. N. B. O. ‘Keep-it-tite’”” Washers—For the stem of globe valves. N. B. O. Flat Gaskets and Rings—As is the case with sheet packing, these have demonstrated their fitness every- ‘where.
