Mueller Streamline ABSY3112 Abs Dwv 45 Degree Wye Fitting

Product Description

The MUELLER STREAMLINE ABSY3112 is a 45-degree wye fitting manufactured from ABS plastic for use in drain, waste, and vent (DWV) piping systems. It features a 3-inch by 3-inch by 1.5-inch configuration with hub connections on all three openings, allowing it to branch a 1.5-inch line off a 3-inch mainline at a 45-degree angle. This geometry reduces turbulence and supports proper drainage flow. Licensed plumbers install this fitting in residential and light commercial DWV rough-in work where a sanitary branch connection is required.

This fitting is suited for above-grade and in-wall DWV applications in residential construction and renovation projects. The 45-degree wye configuration is commonly used when connecting a lavatory, laundry, or secondary drain branch into a 3-inch soil or waste stack. All three ports use a hub-style socket connection, accepting solvent-cemented ABS pipe of the corresponding diameter. It is not intended for pressure piping, potable water supply, or below-grade applications where alternate materials may be required by code.

Key Features

• 45-degree wye angle reduces flow turbulence compared to 90-degree tee configurations
• Three hub connections accept solvent-welded ABS pipe for a secure, leak-resistant joint
• 3 inches x 3 inches x 1.5 inches sizing supports branch connections from a 3-inch mainline
• ABS plastic construction is lightweight and resistant to household drain chemicals
• Designed for DWV service in drain, waste, and vent piping systems

Compatibility

Designed as an OEM-style replacement or new-installation fitting for ABS DWV piping systems requiring a 3-inch x 3-inch x 1.5-inch 45-degree wye hub connection.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local code. Shut off water supply and ensure the drain line is clear and dry before cutting into existing pipe. Use ABS-rated solvent cement and primer as required by the manufacturer and local code. Do not use this fitting for pressurized supply lines or applications outside its rated DWV service.
