Mueller Industries 2890 Abs 45 Degree Dwv Elbow 1-1/2 in

Product Description

The MUELLER INDUSTRIES 2890 is a 1-1/2 inch ABS 45-degree street elbow rated for DWV (drain, waste, and vent) applications. The spigot x hub configuration allows direct connection into a hub-end fitting without a coupling, simplifying inline changes of direction. Constructed in ABS thermoplastic, this elbow handles residential and commercial drainage piping, mechanical systems, and a broad range of low-pressure fluid and gas services. At 0.13 pounds, it is lightweight and easy to position during rough-in work. The fitting carries a 50-year warranty, reflecting long service life in properly installed systems.

This elbow is suited for residential and commercial plumbing drain and vent stacks, hydronic heating systems using glycol, chilled water lines, compressed air systems up to 200 psi, non-medical gas lines up to 140 psi, low-pressure steam up to 15 psi, and vacuum systems up to 24.5 inches of mercury at 68 degrees F. Licensed plumbers install this fitting during rough-in framing stages and remodel work where a 45-degree change of direction is needed in a drain or vent run.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and local amendments. Ensure all water or fluid flow is shut off and the line is depressurized before cutting into an existing system. ABS street elbows are joined using ABS solvent cement applied to both the spigot end and the receiving hub; follow cement manufacturer cure times before restoring flow. Do not use this fitting in applications that exceed the rated pressures or temperatures for ABS thermoplastic pipe and fittings.
