Mueller Streamline 6377 Pvc Dwv Trap Adapter 1-1/2 in Hub X Slip

Product Description

The MUELLER STREAMLINE 6377 is a PVC DWV Desanco trap adapter fitting designed for drain, waste, and vent piping systems. It features a hub by slip joint end connection and is manufactured from PVC to deliver strong resistance to chemicals and corrosion in demanding plumbing environments. The smooth interior walls minimize scaling and support unrestricted flow. This adapter is sized at 1-1/2 inches on both the hub and slip joint ends and includes a one-piece poly nut for a secure, leak-resistant connection. Licensed plumbers and journeyman pipefitters install this fitting in residential and light commercial DWV applications.

This fitting is suited for drain, waste, and vent installations where a hub connection must transition to a slip joint, a common configuration at fixture trap arms beneath sinks and lavatories. It performs reliably in both chemical drain service and standard gravity-flow DWV systems. Dimensional consistency across the product line ensures straightforward integration with standard PVC DWV pipe and fittings. Mueller Streamline serves as a national agent for CPF DWV, backing this product with broad distribution and consistent quality control.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC).

Use appropriate PVC primer and solvent cement on the hub connection; the slip joint side is secured with the included poly nut and requires no solvent bonding. Inspect the slip joint washer seating before tightening to ensure a watertight seal.
