Mueller Streamline 6395 Pvc Dwv Reducing Trap Adapter

Product Description

The MUELLER STREAMLINE 6395 is a reducing trap adapter fitting designed for drain, waste, and vent (DWV) piping systems. It connects a 1-1/2 inch hub inlet to a 1-1/4 inch slip joint outlet, making it a common solution when transitioning between pipe sizes at trap connections. The fitting is manufactured from PVC, offering strong resistance to chemicals and corrosion. A smooth interior wall minimizes scaling and supports unrestricted flow. The one-piece poly nut is included for a secure slip joint connection. Licensed plumbers and pipefitters install this fitting in residential and light commercial DWV applications.

This fitting is used where a sink drain, lavatory, or fixture trap must connect to a larger drain line. The hub end accepts standard 1-1/2 inch PVC pipe with solvent cement, while the slip joint end accommodates a 1-1/4 inch trap arm or drain tube. Its chemical and corrosion resistance makes it suitable for environments where mild chemical drainage is present. The reducing design eliminates the need for a separate bushing in many common trap-to-drain installations.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for residential and light commercial PVC DWV drain systems requiring a 1-1/2 inch hub by 1-1/4 inch slip joint reducing trap adapter connection.

Installation Notes

Installation is performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and ensure the drain line is clear before beginning work. The hub end is solvent-cemented to schedule-appropriate PVC pipe using an approved PVC primer and cement. The slip joint end is secured with the included poly nut and should not be overtightened, as PVC threads and slip joint nuts can crack under excessive force.
