This standard may also be used for fittings with push-on joints or such other joints as may be agreed on at the time of purchase. For the 3- to 24-in. (75- to 600-mm) size range, ductile-iron mechanical-joint fittings and ductile-iron push-on-joint fittings are rated for 350 psi (2413 kPa) working pressure; ductile-iron flange-joint fittings are rated for 250 psi (1724 kPa) working pressure; and gray-iron fittings having all types of joints covered by this standard are rated for 150 or 250 psi (1034 or 1724 kPa) working pressures, as shown in the tables. For the 30- to 48-in.
