Mueller Streamline PDWV4804-4IN Pvc Dwv Adapter 4 in

Product Description

The MUELLER STREAMLINE PDWV4804-4IN is a 4-inch PVC DWV adapter fitting designed to transition between a hub (socket) connection and a male NPT threaded connection in drain, waste, and vent piping systems. This fitting is manufactured from PVC, making it resistant to common drain-line chemicals and corrosion. It is used to connect smooth-end PVC pipe into a female-threaded fitting or threaded port, bridging two different joining methods in a single transition. Licensed plumbers install this fitting during new construction and retrofit DWV work.

This adapter is suited for residential and light commercial drain, waste, and vent applications where a PVC hub inlet must transition to a male NPT threaded outlet. Typical install scenarios include connecting PVC DWV pipe into threaded cleanouts, threaded trap adapters, or threaded ported drain bodies. The 4-inch size is commonly found in main drain lines, closet flanges, and building drain assemblies.

Key Features

• Hub inlet accepts 4-inch PVC pipe for solvent-weld connection
• Male NPT threaded outlet for connection into female-threaded fittings or ports
• PVC construction resists corrosion and common drain-line chemicals
• Transitions between two joining methods in a single fitting
• Sized for 4-inch DWV piping, suitable for main drain and vent line use

Compatibility

Designed as an OEM-style replacement adapter for 4-inch PVC DWV piping systems using hub and male NPT threaded connections in residential and light commercial plumbing installations.

Installation Notes

This fitting is installed by licensed plumbers in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off water supply and ensure the drain line is cleared before beginning work. The hub end requires approved PVC solvent cement applied per the cement manufacturer instructions; the male NPT end requires thread sealant tape or compound rated for plastic fittings. Do not overtighten the threaded connection, as PVC threads can crack under excess torque.
