The ASC Engineered Solutions 318909363 is a black cast iron hex bushing designed to reduce pipe size in threaded piping systems. This fitting connects a 6-inch female threaded inlet to a 3-inch male threaded outlet, allowing transitions between different pipe diameters in a single fitting. At 7.86 pounds, it is a heavy-duty component suited for demanding industrial and commercial plumbing applications. The hex body provides flat wrench surfaces for proper torque during installation. Licensed plumbers and pipefitters typically handle this type of fitting in new construction and retrofit work.
This hex bushing is used in threaded cast iron piping systems found in commercial and industrial facilities, as well as heavy-duty residential applications. It is appropriate for drain, waste, and vent systems as well as certain water and gas distribution lines where cast iron fittings are specified. The black coating provides corrosion resistance and is consistent with standard black iron pipe system aesthetics. Domestically manufactured, this fitting meets expectations for quality in professional piping installations.
Designed as an OEM-style replacement or new-installation fitting for threaded cast iron pipe systems requiring a 6-inch to 3-inch diameter reduction.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and IPC standards. Shut off and depressurize the pipe system fully before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Use a pipe wrench on the hex body flats to tighten the fitting; avoid over-tightening, which can crack cast iron.
