Nibco PRESRED112 Copper Press Reducing Coupling 1x1/2 in

Product Description

The NIBCO PRESRED112 is a copper press-by-press reducing coupling designed for joining dissimilar-diameter copper tubing without soldering. It connects 1-inch tubing on one end to 1/2-inch tubing on the other using a press-fit connection, creating a permanent, leak-tight joint through cold-press crimping. This fitting is suited for potable water supply, hydronic heating, and general plumbing distribution systems. Licensed plumbers and pipefitters install this type of fitting where open-flame work is restricted or where faster installation is a priority over traditional sweat connections.

This reducing coupling fits residential and light commercial plumbing applications where copper tubing transitions between 1-inch and 1/2-inch line sizes are required. Typical install scenarios include branch takeoffs in domestic water distribution, hydronic radiant systems, and mechanical room piping. The press-fit design is compatible with standard press-jaw tooling from major press tool manufacturers and is well suited for retrofit work, occupied spaces, or any environment where torch use is impractical.

Key Features

• Press-by-press end connections eliminate the need for open-flame soldering
• Reduces from 1-inch to 1/2-inch copper tubing in a single fitting
• Copper construction provides corrosion resistance in potable water and hydronic systems
• Cold-press installation creates a permanent, repeatable joint
• Compatible with standard press tooling used across the plumbing trade

Compatibility

Designed as an OEM-style press fitting for use with standard copper tubing in residential and commercial plumbing systems. Consult applicable local codes and the fitting manufacturer for verified tubing type and system pressure ratings before installation.

Installation Notes

Installation should be performed by a licensed plumber in accordance with IPC or applicable local plumbing codes. Depressurize and drain the system completely before cutting into existing lines. Use the correct press jaw size for each end of this reducing coupling, as the 1-inch and 1/2-inch ends require different jaw sets. Inspect the EPDM or silicone press ring for proper seating in the fitting socket before pressing to ensure a leak-free joint.
