Mueller Streamline 5910 Pvc Dwv Flush Bushing 4x2 in

Product Description

The MUELLER STREAMLINE 5910 is a PVC DWV flush bushing designed to reduce a 4-inch hub connection down to a 2-inch spigot in drain, waste, and vent piping systems. With a spigot x hub end connection, this bushing integrates directly into standard DWV assemblies without requiring additional adapters. The PVC construction meets ASTM D2665, F1498, D331, and D1784 material specifications and is listed to NSF 14 and UPC standards. Smooth interior walls minimize scaling and support consistent flow. Licensed plumbers and pipefitters install this fitting in both residential and light commercial drain systems.

This bushing is suited for DWV applications where a 4-inch line must transition to a 2-inch branch or termination point. It is also appropriate for chemical and corrosion-resistant piping applications where PVC is the specified material. The flush bushing profile keeps the fitting seated within the hub of the adjacent fitting, maintaining a low-profile connection that works within tight or compact rough-in conditions. It is a standard component in residential bathroom, kitchen, and utility drain assemblies as well as commercial DWV rough-in work.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code and applicable local codes.
