Mueller Streamline PDWVBUSHSPH42 Pvc Dwv Bushing

Product Description

The MUELLER STREAMLINE PDWVBUSHSPH42 is a PVC DWV reducing bushing used to transition drain, waste, and vent piping from a 4-inch hub down to a 2-inch spigot connection. Made for gravity-flow drainage systems, this bushing installs inside an existing hub fitting, allowing the downstream line to step down in diameter without adding a coupling or additional fitting. Licensed plumbers and pipe installers use this bushing when reconfiguring residential or light commercial DWV runs during new construction or remodel work.

This bushing fits into standard 4-inch PVC DWV hub fittings and accepts a 2-inch spigot pipe or fitting on the outlet end. It is suited for horizontal drain lines, vertical stacks, and vent piping in residential and light commercial plumbing systems where a reduction in pipe diameter is required. The spigot-by-hub (S x H) configuration simplifies inline transitions and keeps the fitting count low in tight framing bays.

Key Features

• Reduces 4-inch hub to 2-inch spigot in a single fitting
• Spigot x Hub end configuration for direct inline installation
• PVC construction compatible with standard solvent-weld cement
• Designed for gravity-flow DWV applications — not for pressure service
• Low profile bushing design minimizes space requirements inside hub fittings

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 4-inch x 2-inch PVC DWV piping systems following ASTM D2665 and D3034 standards for drain, waste, and vent service.

Installation Notes

Installation is performed by licensed plumbers in accordance with the International Plumbing Code (IPC) and local adopted codes. Clean and deburr pipe ends before applying PVC primer and solvent-weld cement to both the bushing and the receiving hub. This fitting is rated for DWV gravity-flow service only — do not use in pressurized water supply lines. Ensure proper slope on horizontal drain runs per code requirements before cementing connections.
