The MUELLER STREAMLINE ABSBEND163 is a 3-inch ABS DWV 60-degree elbow fitting with a hub-by-hub connection designed for drain, waste, and vent piping systems. Molded from acrylonitrile butadiene styrene (ABS) plastic, this elbow changes pipe direction at 60 degrees and is joined using solvent cement on both ends. It is a standard fitting for residential and light commercial DWV rough-in work installed by licensed plumbers and pipefitters.
This fitting is used in gravity-flow drain, waste, and vent systems where a 60-degree directional change is required. Common applications include horizontal drain runs, branch offsets, and vent stack transitions in residential construction and remodel work. The hub-by-hub end configuration accepts standard 3-inch ABS pipe on both ends, making it a direct-fit solution for new installations or repairs in ABS DWV systems.
Designed as an OEM-style replacement and standard fitting for 3-inch ABS DWV piping systems in residential and light commercial drain, waste, and vent applications.
Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Before beginning work, shut off water supply and ensure the drain system is cleared of flow. Clean and dry pipe ends before applying ABS solvent cement, and allow full cure time before pressure-testing the system. Do not use ABS fittings with PVC pipe without an approved transition coupling.
