Tigre Usa Inc 36-700 Sewer Drain Reducing Coupling

Product Description

The TIGRE USA INC 36-700 is a sewer and drain reducing coupling designed to connect a 6-inch pipe to a 4-inch pipe in gravity-drain waste systems. This fitting creates a smooth, secure transition between two pipe diameters, maintaining flow integrity and preventing leaks at the joint. It is a standard component in residential and light commercial drain, waste, and vent (DWV) plumbing systems. Licensed plumbers and pipefitters install this type of coupling during new construction, remodel work, and repair projects where a pipe size reduction is required along a horizontal or vertical drain run.

This reducing coupling is suited for sewer and drain applications where a 6-inch line must step down to a 4-inch line. Typical install scenarios include main drain trunk reductions, connections between building sewers and interior drain stacks, and below-grade piping transitions. The fitting is sold in a package quantity of 10 units, making it practical for contractors working on multi-unit or larger-scale plumbing projects.

Key Features

• Reduces a 6-inch pipe connection to a 4-inch pipe connection in a single fitting
• Designed for sewer and drain service in DWV piping systems
• Package quantity of 10 units per order unit of measure
• Compact reducing coupling form factor simplifies pipe layout and reduces the need for additional adapters

Compatibility

Designed as an OEM-style replacement and standard-fit coupling for sewer and drain piping systems requiring a 6-inch to 4-inch diameter reduction.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local plumbing codes. Shut off water flow and verify the drain line is clear and depressurized before cutting into any existing piping. Ensure pipe ends are cleanly cut, deburred, and properly primed and solvent-cemented if joining PVC or ABS pipe. Support the pipe assembly adequately on both sides of the fitting to prevent stress on the joint.
