Tigre Usa Inc 36-660 4 Inch Sewer Drain Adapter Coupling

Product Description

The TIGRE USA INC 36-660 is a 4-inch sewer drain adapter coupling designed to connect sewer hub pipe to PVC-DWV hub pipe in drainage, waste, and vent systems. It allows straight pipe runs to transition between sewer drain and PVC drain materials without additional fittings. The coupling is sold in packages of 5 units, each weighing 2.25 pounds. Licensed plumbers and drain system installers rely on this fitting to make clean, code-appropriate transitions in residential and light commercial DWV systems.

This fitting is used in drainage, waste, and vent applications where a sewer drain line must connect to a PVC-DWV system. Typical install scenarios include underground sewer lateral connections, in-slab drain tie-ins, and below-grade waste line transitions. The 4-inch size suits main drain lines and branch takeoffs common in residential construction and remodel work.

Key Features

• Connects sewer hub pipe to PVC-DWV hub pipe in a single fitting
• 4-inch diameter suits main drain and large branch applications
• Designed for straight pipe run joins without offset or angle
• Sold in a 5-unit package for multi-connection jobs

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 4-inch sewer hub to PVC-DWV hub connections in residential and light commercial drain, waste, and vent systems.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC and local plumbing code requirements. Shut off water supply and relieve system pressure before beginning work on any active drain line. Ensure pipe ends are cleanly cut, deburred, and properly primed and solvent-cemented where PVC connections are made. Do not force misaligned pipe into the hub ends, as this can compromise the seal.
