Nibco, Inc. C600 1-1/4" x 3/4" Copper Reducer Trap

Copper Reducer Trap for Plumbing Systems

The Nibco C600 is a wrot copper reducer fitting designed to connect 1-1/4 inch tubing to 3/4 inch tubing in drain applications. It suits plumbers and maintenance teams joining dissimilar copper pipe sizes in residential or commercial installations. The C x C connection type allows direct soldering without additional adapters. This component handles standard drain flow requirements in new or retrofit projects.

Pressure and Temperature Operating Limits

The fitting withstands a maximum pressure of 439 psi at 100 degrees Fahrenheit and operates across a temperature range from -20 degrees to 400 degrees Fahrenheit. These limits define safe use in hot water lines, heating circuits, and cold environments. Compliance with ASME/ANSI B 16.22 ensures dimensional consistency for reliable joints. Exceeding the stated pressure or temperature range risks joint failure or leaks.

Replaces Mismatched Fittings and Field Fabrication

This reducer replaces improvised bushings or mismatched fittings that compromise flow and code compliance. The jump is worth it when a single factory-made fitting eliminates extra joints, reduces solder points, and meets inspection standards. It is not suited for systems requiring non-copper materials, press-fit connections, or sizes outside the 1-1/4 by 3/4 inch nominal range. Builders needing other diameter transitions must source a different model.
