Mueller Streamline 5888 Pvc Dwv 4 Inch Hub 45 Elbow

Product Description

The MUELLER STREAMLINE 5888 is a 4-inch PVC DWV hub by hub 45-degree elbow fitting designed for drain, waste, and vent piping systems. Built to ASTM D2665, F1498, D331, and D1784 material specifications, this fitting delivers consistent dimensional integrity for reliable, leak-free connections. The smooth interior bore reduces friction and prevents scaling buildup, supporting unobstructed flow through the drain line. Licensed plumbers and pipe fitters install this fitting as part of new construction or retrofit DWV systems in both residential and commercial applications.

This elbow is suited for horizontal and vertical DWV runs where a gradual 45-degree change of direction is required. Typical applications include sanitary drain lines, chemical-resistant waste piping, and industrial drainage systems. The hub by hub end connections accept standard 4-inch PVC pipe, making integration straightforward in standard schedule DWV assemblies. It meets NSF 14 and UPC certification requirements, making it appropriate for use in jurisdictions that require listed fittings for sanitary and DWV installations.

Key Features

• 45-degree elbow geometry for gradual directional change in DWV piping runs
• Hub by hub end connections sized at 4 inches on both ends
• PVC construction provides resistance to corrosion and a broad range of chemicals
• Smooth interior walls minimize flow restriction and resist scaling
• Meets NSF 14 and UPC standards for use in certified DWV installations
• Complies with ASTM D2665, F1498, D331, and D1784 material specifications

Compatibility

Designed as an OEM-style DWV fitting for use in 4-inch PVC drain, waste, and vent piping systems meeting ASTM D2665 and related standards.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off water supply and ensure the drain line is depressurized and empty before cutting into an existing system. Solvent-cement the hub connections using a PVC primer and cement rated for DWV service, following the cement manufacturer's pot life and cure time guidance before restoring flow. Do not apply excessive force when seating pipe into the hub, as this fitting is sized for standard-clearance DWV pipe.
