Nibco PRESRED11434 Copper Press Reducing Coupling

Product Description

The NIBCO PRESRED11434 is a copper press-style reducing coupling designed to connect two different pipe sizes without soldering. It joins a 1-1/4 inch pipe to a 3/4 inch pipe using a press x press end configuration, making it a practical solution for reducing transitions in closed water systems. Plumbers and pipefitters install this fitting wherever a tool-based press connection is preferred over an open-flame sweat joint. The press design speeds up installation and eliminates the need for a torch, flux, or solder, which is especially useful in occupied buildings or tight spaces where fire hazard is a concern.

This reducing coupling is suited for residential and light commercial plumbing applications involving domestic water supply lines, recirculation systems, and hydronic heating systems. It is installed in-line wherever a pipe size reduction is required, and the press x press configuration means both ends accept a standard press tool jaw. Licensed plumbers performing pipe retrofits, system upgrades, or new rough-in work will find this fitting compatible with standard copper press tooling used across the trade.

Key Features

• Press x press end configuration eliminates need for soldering or open flame
• Reduces from 1-1/4 inch to 3/4 inch in a single fitting
• Copper construction provides corrosion resistance suitable for potable water service
• Compatible with standard press tool jaws used for copper press fittings
• Compact inline profile for use in confined spaces and wall cavities

Compatibility

Designed as an OEM-style press fitting for use with standard copper press systems in residential and light commercial plumbing installations where 1-1/4 inch to 3/4 inch size reductions are required.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and ASME B16.18 or B16.22 standards where required. Shut off the water supply and relieve system pressure before cutting into any existing line. A compatible press tool with the correct jaw size must be used for each end of the fitting. Inspect the pipe ends for burrs or debris and ensure the pipe is fully inserted to the fitting stop before pressing.
