Mueller Industries 2873 Abs Long Turn 90 Degree Dwv Elbow 3 in

Product Description

The MUELLER INDUSTRIES 2873 is a 3-inch ABS long turn 90 degree elbow rated for DWV (drain, waste, and vent) applications. Constructed from ABS plastic with hub-style connections on both ends, this fitting accepts standard 3-inch plastic pipe and provides a sweeping 90 degree change of direction with a long-radius bend that reduces flow restriction compared to short-turn elbows. At 7.63 inches in length and 4 inches in width, it fits within standard joist bays and wall cavities. Licensed plumbers and pipe fitters install this fitting during rough-in on residential and light commercial drain systems.

The 2873 is used in residential and light commercial DWV piping systems where a gradual 90 degree turn is needed on a 3-inch drain or vent line. Common install locations include under-slab drain runs, horizontal branch lines, and vent stack transitions. The long-sweep geometry helps maintain flow velocity and reduces the likelihood of solids accumulation at the bend, making it a preferred choice over short-turn elbows on drain lines carrying waste.

Key Features

• Long-turn sweep radius reduces flow restriction on 3-inch DWV drain lines
• ABS plastic construction resists corrosion and chemical attack common in drain environments
• Hub x Hub connection accepts standard 3-inch ABS pipe with solvent cement
• Compact envelope at 7.63 inches length and 4 inches width fits standard framing bays
• Lightweight at 0.89 pounds for easy single-hand positioning during rough-in

Compatibility

Designed as an OEM-style replacement or new-installation fitting for residential and light commercial ABS DWV piping systems using 3-inch nominal pipe.

Installation Notes

Installation is performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off water supply and verify the drain line is empty before cutting into existing piping. Clean and dry all mating surfaces, then apply ABS solvent cement per manufacturer instructions, allowing full cure time before pressurizing or back-filling. Support horizontal runs per code-required hanger spacing to prevent sagging at the fitting joint.
