The ASC ENGINEERED SOLUTIONS 318909207 is a black cast iron hex bushing designed to reduce pipe size in threaded piping systems. The bushing measures 5 inches by 2 inches, transitioning from a 5-inch female thread to a 2-inch male thread. At 4.98 pounds, this is a heavy-duty fitting built for demanding plumbing and mechanical applications. The hex body allows standard wrench engagement for proper tightening. Licensed plumbers and pipefitters install this type of fitting in both new construction and retrofit work where pipe diameter reduction is required in a single threaded connection.
This cast iron hex bushing is suited for industrial and commercial piping systems where cast iron fittings are specified. Common applications include drainage, waste, and vent (DWV) systems, as well as low-pressure piping where threaded cast iron fittings meet code requirements. The 5-inch to 2-inch reduction makes it appropriate for main-to-branch transitions in larger piping assemblies. Domestically manufactured, this fitting is appropriate for installations requiring US-made components.
Designed as an OEM-style replacement or new-installation fitting for threaded cast iron piping systems requiring a 5-inch to 2-inch pipe size reduction.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and depressurize the line before beginning work. Apply appropriate thread sealant or PTFE tape to the male threads before assembly. Use a pipe wrench on the hex body to achieve a secure, leak-free connection without over-stressing the fitting.
