Nibco PRESRED3412 Copper Press Reducing Coupling 3/4x1/2

Product Description

The NIBCO PRESRED3412 is a copper press-fit reducing coupling designed to join 3/4-inch pipe to 1/2-inch pipe using a press-style connection on both ends. No open flame is required for installation, making it a fast, reliable alternative to soldered fittings in both new construction and retrofit applications. The fitting is machined from copper to ensure durability and compatibility with potable water systems. Licensed plumbers and pipefitters use this fitting when transitioning between two common pipe diameters in residential and light commercial plumbing systems.

This reducing coupling is suited for residential and light commercial water distribution systems where a press-style connection is preferred or required. It is commonly installed in tight spaces or areas where torch work is restricted, such as near insulation, wood framing, or fire-rated assemblies. The press-by-press end configuration allows for tool-based crimping on both sides of the fitting without the need for soldering equipment.

Key Features

• Press-fit on both ends eliminates the need for open-flame soldering
• Copper construction for corrosion resistance and long service life
• 3/4-inch inlet to 1/2-inch outlet for in-line pipe diameter reduction
• Compatible with standard press tooling used in the trade
• Suitable for potable water and general plumbing distribution lines

Compatibility

Designed as an OEM-style replacement or new-installation copper press reducing coupling for residential and light commercial plumbing systems using 3/4-inch and 1/2-inch press-fit pipe connections.

Installation Notes

Installation must be performed by a licensed plumber using a calibrated press tool with the correct jaw size for each end of the fitting. Shut off the water supply and depressurize the line before installation. Verify that pipe ends are clean, deburred, and fully seated into the fitting socket before pressing. Follow local plumbing codes, including applicable IPC requirements, for press-fit fitting installation and inspection.
