ABSTRACT:
Cast iron fittings are coupled with reducer fittings in a fluid handling network to reduce the flow diameter in various pipe sections of the network. Each main fitting and reducer fitting has two or more tabs about their mating open ends which are aligned and connected one to the other to maintain the fittings coupled together. Reducer fittings having standard size, large diameter ends, are provided with variously sized smaller diameter ends to selectively reduce the flow. The reducer fittings are straight-through sections useful with main fittings of various types, including Tees, elbows, right-angle bends and the like.
