Mueller Streamline PDWVBEND18SPH4 Pvc Dwv 1/8 Bend

Product Description

The MUELLER STREAMLINE PDWVBEND18SPH4 is a 4-inch PVC DWV 1/8 bend fitting designed to redirect drain, waste, and vent lines at a 45-degree angle. The spigot x hub (SXH) end configuration allows it to connect into an existing hub fitting on one end while accepting a spigot or pipe on the other. This fitting is manufactured from PVC, making it lightweight, corrosion-resistant, and compatible with standard solvent-weld joining methods. Licensed plumbers and drain-line installers use this fitting when a gradual directional change is required in gravity-flow DWV systems.

This 1/8 bend is suited for residential and light commercial plumbing applications where drain, waste, and vent piping requires a 45-degree change in direction. The 4-inch diameter accommodates main drain lines, closet flanges, and branch connections common in sanitary drainage systems. It is installed in horizontal, vertical, and offset drain runs per applicable plumbing code requirements.

Key Features

• 45-degree directional change for gradual flow redirection in DWV systems
• 4-inch diameter fits standard main drain and waste line applications
• Spigot x hub (SXH) end configuration for flexible connection to existing fittings
• PVC construction resists corrosion and chemical degradation in drain service
• Solvent-weld joints compatible with standard PVC cement and primer

Compatibility

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

Installation Notes

Installation should be performed by a licensed plumber in accordance with the applicable International Plumbing Code (IPC) or local plumbing authority requirements. Shut off water supply and ensure the drain line is empty and dry before cutting into existing pipe. Clean and deburr all pipe ends, apply approved PVC primer, then apply PVC solvent cement to both the spigot end and the hub socket before joining. Allow adequate cure time before restoring flow to the line.
