Mueller Streamline ABSY2112112 Abs Dwv 45 Deg Wye Fitting

Product Description

The MUELLER STREAMLINE ABSY2112112 is an ABS DWV 45-degree wye fitting used in residential and light commercial drain, waste, and vent piping systems. The fitting connects a 2-inch main line to two 1-1/2-inch branch lines using a hub-by-hub-by-hub configuration. The 45-degree angle allows branch lines to enter the main drain at a gradual slope, reducing turbulence and promoting smooth drainage flow. Molded from ABS plastic, this fitting is lightweight, corrosion-resistant, and solvent-weld compatible. Licensed plumbers and pipefitters install this type of fitting during rough-in work on new construction or remodel drain systems.

This fitting is suited for residential and light commercial DWV applications including sink drains, lavatory branches, and fixture connections that tie into a larger 2-inch main stack or horizontal drain run. The 1-1/2-inch hub inlets are sized for standard lavatory, kitchen sink, and washing machine drain lines. The 45-degree wye geometry complies with typical DWV code requirements for drain branch fittings where a gradual change of direction is specified rather than a 90-degree tee configuration.

Key Features

• 45-degree wye angle supports code-compliant branch connections in DWV systems
• Hub x Hub x Hub end connections accept solvent-weld ABS pipe on all three ports
• 2-inch main inlet with two 1-1/2-inch branch hubs for reducing branch connections
• ABS plastic construction resists corrosion and chemical attack from drain waste
• Lightweight design simplifies handling and installation during rough-in

Compatibility

Designed as an OEM-style replacement or new-installation fitting for ABS DWV piping systems using standard hub-end solvent-weld connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local plumbing codes. Shut off the water supply and ensure the drain system is depressurized and dry before cutting into existing lines. Use an approved ABS solvent cement and primer where required by code, and allow full cure time before restoring flow. Do not use this fitting on pressurized water supply lines.
