Mueller Streamline 6138 Pvc Dwv Reducing Hub Wye 6x6x3

Product Description

The MUELLER STREAMLINE 6138 is a reducing PVC DWV hub wye fitting designed for drain, waste, and vent piping systems in industrial and sanitary applications. Configured at a 45-degree angle with hub x hub x hub end connections, this fitting transitions a 6-inch mainline to a 3-inch branch outlet. The PVC construction meets ASTM D2665, F1498, D331, and D1784 material specifications, delivering consistent chemical and corrosion resistance. Smooth interior walls minimize scaling and promote unrestricted flow. Licensed plumbers and pipefitters install this fitting in below-grade and above-grade DWV assemblies where a reducing lateral branch is required.

This fitting is suited for residential and commercial DWV installations including sanitary drain systems, industrial waste lines, and chemical-resistant piping applications. The reducing configuration accommodates 6-inch main runs branching to 3-inch lateral lines, a common arrangement in multi-fixture or multi-floor drain systems. The hub connection style accepts standard PVC pipe ends with solvent-cement jointing, consistent with typical DWV installation practices. It carries NSF 14 and UPC certifications, confirming compliance with national plumbing standards for sanitary use.

Key Features

• Reducing wye configuration: 6 inches x 6 inches x 3 inches with a 45-degree branch angle
• Hub x hub x hub end connections for solvent-cement assembly
• PVC construction resistant to chemicals and corrosion
• Smooth interior walls reduce scaling and support free flow
• Meets ASTM D2665, F1498, D331, and D1784 material specifications
• NSF 14 and UPC certified for sanitary and industrial DWV use

Compatibility

Designed as an OEM-style replacement and new-installation fitting for PVC DWV piping systems requiring a 6-inch x 6-inch x 3-inch reducing hub wye, suitable for sanitary, industrial, and chemical-resistant drain, waste, and vent applications meeting NSF 14 and UPC standards.

Installation Notes

Installation is performed by licensed plumbers in accordance with the International Plumbing Code and applicable local codes. Shut off flow and ensure the piping system is drained and dry before cutting into an existing line. Hub connections require proper solvent-cement primer and cement rated for PVC DWV applications. Support the fitting per code-specified hanger intervals to prevent sag or joint stress.
