Mueller Streamline 6137 Pvc Dwv Reducing Hub Wye 45 Degree

Product Description

The MUELLER STREAMLINE 6137 is a reducing PVC DWV hub wye fitting designed for drain, waste, and vent piping systems. It features a 45-degree branch angle and connects 6-inch by 6-inch by 4-inch hub ends, allowing a 4-inch branch line to tie into a 6-inch main line. The PVC construction meets ASTM D2665, F1498, D331, and D1784 material specifications and is certified to NSF 14 and UPC standards. Smooth interior walls resist scale buildup and support free-flowing drainage. Licensed plumbers install this fitting in new construction and retrofit DWV systems where a reducing lateral branch connection is required.

This fitting is suited for residential and commercial DWV applications including sanitary drainage, industrial waste piping, and systems handling corrosive or chemical effluent. The hub-by-hub-by-hub end connections accept solvent-cemented PVC pipe at all three ports. The 45-degree angle is standard for sanitary wye layouts that require a gradual branch entry to maintain flow velocity and reduce the risk of solids accumulation at the junction.

Compatibility

Designed as an OEM-style DWV replacement and new-installation fitting for PVC drain, waste, and vent piping systems requiring a 45-degree reducing hub wye at 6 inches x 6 inches x 4 inches nominal dimensions.

Installation Notes

Installation of PVC DWV fittings is typically performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off water supply and ensure the piping system is depressurized and drained before cutting into an existing line. Use a compatible PVC primer and solvent cement rated for DWV applications, following the cement manufacturer's cure time before restoring flow. Do not use this fitting on pressurized supply lines or applications outside its rated DWV and sanitary scope.
