The ASC Engineered Solutions 300002409 is a 4-inch black cast iron 90-degree elbow designed for use in drain, waste, and vent piping systems. This fitting changes flow direction by 90 degrees and is manufactured domestically from cast iron with a black coating finish. Weighing 12.26 pounds, the fitting offers the mass and durability expected from cast iron construction in demanding commercial and residential plumbing applications. Licensed plumbers and pipefitters are the primary installers of this type of fitting.
This elbow is suited for use in drain, waste, and vent (DWV) piping systems where a 90-degree directional change is required at a 4-inch pipe diameter. It is appropriate for both new construction and retrofit installations in residential and light commercial buildings. The black coating provides corrosion resistance for above-ground and in-wall applications typical of cast iron DWV systems.
Designed as an OEM-style replacement or new-install fitting for 4-inch cast iron drain, waste, and vent piping systems.
Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the water supply and verify the line is depressurized before beginning any work. Cast iron fittings of this type are typically joined using hub-and-spigot lead and oakum joints or no-hub couplings with band clamps, depending on system configuration. Support the fitting adequately per code requirements to prevent stress on adjacent piping.
