Mueller Streamline PDWV48032112 Pvc Dwv Adapter

Product Description

The MUELLER STREAMLINE PDWV48032112 is a PVC DWV adapter fitting designed to transition between a 2-inch spigot (SPG) connection and a 1-1/2-inch female iron pipe (FIP) threaded connection. This fitting is manufactured from PVC, making it lightweight, corrosion-resistant, and suitable for drain, waste, and vent (DWV) piping systems. Plumbers and pipefitters use this adapter when joining dissimilar connection types within a gravity-flow drainage system. It is a direct, no-frills solution for connecting smooth-socket pipe into a female-threaded fitting without additional adapters.

This adapter is intended for use in residential and light commercial DWV applications, including drain lines, waste stacks, and vent piping. The spigot end slides into a hub fitting, while the FIP end accepts male-threaded pipe or fittings. Typical installations include under-sink drain assemblies, floor drain connections, and branch line transitions within interior PVC drain systems.

Key Features

• PVC construction provides corrosion resistance and long service life in drainage applications
• 2-inch spigot end connects directly into a standard hub fitting
• 1-1/2-inch female iron pipe thread accepts standard male-threaded PVC or ABS fittings
• Designed for gravity-flow drain, waste, and vent systems
• Lightweight design simplifies handling and installation in tight spaces

Compatibility

Designed as an OEM-style replacement fitting for residential and light commercial PVC DWV piping systems requiring a 2-inch spigot to 1-1/2-inch female iron pipe thread transition.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off water supply and ensure the drain system is depressurized before beginning work. Apply PVC primer and solvent cement to the spigot connection per manufacturer guidelines; use appropriate thread sealant on the FIP connection. Do not overtighten threaded connections, as PVC threads can crack under excessive torque.
