Nibco PRESRED1121 Copper Press Reducing Coupling

Product Description

The NIBCO PRESRED1121 is a copper press-style reducing coupling designed for joining two different pipe sizes in pressurized plumbing and hydronic systems. It connects 1-1/2 inch pipe to 1 inch pipe using a press x press end configuration, eliminating the need for open flame or solder during installation. Licensed plumbers and pipefitters install this fitting in residential and light commercial water distribution, radiant heating, and mechanical piping systems where a clean, repeatable connection is required.

This reducing coupling is suited for new construction and retrofit applications where pipe sizing transitions occur within a run. The press connection method works with standard copper tubing and is compatible with press-style jaw tooling commonly used in commercial and residential plumbing. It is a practical choice in occupied spaces or tight areas where torch work is restricted or prohibited by code.

Key Features

• Press x press end configuration allows tool-pressed connections without soldering or open flame
• Reducing design transitions 1-1/2 inch pipe to 1 inch pipe in a single fitting
• Copper construction provides corrosion resistance suitable for potable water and hydronic applications
• Compact profile fits tight mechanical spaces and wall cavities

Compatibility

Designed as an OEM-style replacement and standard-fit reducing coupling for copper press piping systems using 1-1/2 inch to 1 inch transitions in residential and commercial plumbing applications.

Installation Notes

Installation requires a calibrated press tool fitted with the correct jaw size for each end of the fitting. Shut off and depressurize the water supply before beginning work. Inspect tubing ends for squareness and remove burrs before inserting into the fitting. Follow all applicable local plumbing codes and manufacturer press-tool guidelines to ensure a leak-free connection.
