Mueller Streamline PDWV4804112 Pvc Dwv Adapter 1-1/2 in

Product Description

The MUELLER STREAMLINE PDWV4804112 is a PVC DWV pipe fitting adapter designed to transition between a hub (socket) connection and a male NPT threaded connection in drain, waste, and vent piping systems. Sized at 1-1/2 inches, this adapter allows plumbers to connect plain-end or hub-style PVC pipe to a male national pipe thread fitting without additional adapters. It is a standard component in residential and light commercial DWV rough-in work, installed by licensed plumbers and pipefitters following applicable plumbing codes.

This adapter is suited for drain, waste, and vent applications in residential construction, remodeling, and repair scenarios. It functions at the junction where a solvent-welded PVC hub system meets a threaded pipe or fitting. Typical uses include connecting PVC DWV pipe runs to threaded trap arms, cleanout plugs, or threaded fixture drains. The 1-1/2 inch size is commonly found in lavatory, kitchen sink, and similar fixture drain lines.

Key Features

• Hub (socket) inlet accepts 1-1/2 inch PVC pipe for solvent-cement joining
• Male NPT outlet connects directly to female-threaded fittings or fixture ports
• PVC construction suitable for DWV service in non-pressure drain and vent lines
• Standard 1-1/2 inch size fits common lavatory and kitchen drain applications
• Lightweight fitting reduces load on fixture drain connections

Compatibility

Designed as an OEM-style replacement and standard fitting for residential and light commercial PVC DWV piping systems using 1-1/2 inch hub and NPT male connections.

Installation Notes

Installation is performed by licensed plumbers in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off water supply and verify the drain line is clear before beginning work. The hub end requires PVC primer and solvent cement applied per manufacturer instructions; do not skip the primer step on DWV fittings. The male NPT end should be joined to female-threaded fittings using thread sealant tape or compound rated for PVC and plastic fittings.
