The iron from which class 125 cast iron fittings are made is held to strict formula by careful chemical analysis and control. Tapping is done on the most modern machines. All tapping's are to USA standards for iron pipe threads. Straightness and correct depth of threads is assured through continuous capable inspection, by careful trained inspectors. Every fitting is hand sorted and inspected to eliminate defective castings. Ward fittings are made to specifications published as American national standards for pipe fittings. A chamfer is cut or cast in all openings, permitting easy entrance of pipe and preventing damage to the first thread in handling and threading. Because of the close attention paid to formula control and the use of modern precision equipment we are able to produce castings of rugged strength and the ability to make a water tight seal.
