2-1/2" Galvanized Countersunk Plugs Square Head Plugs 4 Class 125 NPT threadsWard Class 150 Malleable Iron Fittings are made with the most sophisticated metallurgical and processing controls available. Iron samples are continuously analyzed using spectroscopy to conform the material quality. This sophisticated chemical analysis is complemented by rigorous quality control of incoming raw materials and iron processing. The final casting produced by this detailed attention to quality is a close grained, high strength, non porous
