Bolted transition/reducing coupling for any combination of steel, cast or ductile.
Dresser Style 62 Reducing Couplings are ideal for (1) when making actual reductions in pipe size, (2) when changing the class of pipe, and (3) when joining steel and cast iron pipe. They can be supplied for connections between any two kinds or sizes of pipe. Type I Reducing Couplings are for reductions where the differences in pipe diameters are small, as from standard cast iron to steel of the same nominal size. Standard Style 38 parts are used except the middle ring is swaged on one end. Type II Reducing Couplings are for larger and special reductions outside the range of Type I. They are made from Style 38 parts with anchor rings welded to the middle ring. Two sets of bolts are supplied.
