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.

Questions about this item
Which size should I choose for a 1-1/4 inch to 3/4 inch copper tube reduction?
This reducer fits a nominal 1-1/4 inch tube on one end and a 3/4 inch tube on the other, with outside diameters of 1-3/8 inch and 7/8 inch respectively.
What does the 439 psi rating mean when the fitting is installed in a hot water system?
The 439 psi maximum pressure is rated at 100 Degrees F; at higher temperatures up to 400 Degrees F the allowable pressure will be lower.
What does the ASME/ANSI B 16.22 standard cover for this C x C copper reducer?
It governs the dimensions and tolerances for wrought copper solder-joint pressure fittings, ensuring the cup depths and wall thicknesses match the standard for reliable sweat connections.
