The MUELLER STREAMLINE ABSBEND164 is a 4-inch ABS DWV 60-degree elbow fitting with a hub-by-hub connection configuration. Molded from acrylonitrile butadiene styrene (ABS) plastic, this fitting is designed for drain, waste, and vent (DWV) piping systems in residential and light commercial construction. The 60-degree bend angle makes it suitable for routing drain lines where a standard 45-degree or 90-degree elbow will not align with the intended pipe path. Licensed plumbers and pipefitters install this type of fitting as part of gravity-flow drain and vent rough-in work.
This elbow is used in ABS DWV piping systems for sanitary drain, waste, and vent applications. It is commonly installed in below-slab, in-wall, or above-ceiling drain line configurations where a 60-degree change of direction is required. The hub-by-hub ends accept standard 4-inch ABS pipe solvent-welded on both sides, making it a straightforward component in new construction or remodel drain rough-in projects.
Designed as an OEM-style replacement or new-installation fitting for 4-inch ABS DWV piping systems following applicable plumbing codes.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC) where adopted. Shut off water supply and ensure the drain line is dry before cutting into existing piping. Use ABS-rated solvent cement and primer as required by local code, and allow adequate cure time before pressure-testing or returning the system to service. Do not use this fitting on pressurized supply lines.
