Mueller Streamline DWV90STLFTGC112 Dwv 90 Degree Elbow

Product Description

The MUELLER STREAMLINE DWV90STLFTGC112 is a wrot copper 90-degree elbow fitting designed for drain, waste, and vent (DWV) piping systems. With a 1-1/2 inch Ftg x C (fitting-to-copper) connection, it allows for a clean, soldered 90-degree directional change in the drain line. Wrot copper construction provides consistent wall thickness and a smooth interior bore, which supports proper drainage flow. This fitting is installed by licensed plumbers working on residential and light commercial DWV systems where copper is the specified pipe material.

This elbow is suited for horizontal-to-vertical and vertical-to-horizontal transitions in copper DWV assemblies. The Ftg x C configuration means one end accepts copper tubing into a fitting socket and the other end slips over standard copper tube, making it straightforward to integrate into new construction or remodel work. It is appropriate for above-ground DWV applications as defined by the International Plumbing Code (IPC) and applicable local plumbing codes for copper DWV systems.

Key Features

• 90-degree sweep geometry for directional changes in DWV drain and vent lines
• Wrot copper construction for consistent wall thickness and reliable solder joints
• 1-1/2 inch Ftg x C end connections for integration into standard copper DWV assemblies
• Smooth interior bore supports drainage flow and reduces buildup
• Compatible with standard sweat-solder installation per IPC DWV requirements

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/2 inch copper DWV piping systems in residential and light commercial plumbing applications.

Installation Notes

Installation is performed by a licensed plumber. Shut off the water supply and drain the affected lines fully before cutting into existing piping. Clean all mating surfaces with emery cloth and apply approved flux before soldering; follow ASTM and local code requirements for lead-free solder on potable and DWV systems. Ensure the fitting is properly supported and pitched according to IPC drain-slope requirements before the joint cools.
