Nibco PRESU2 Copper Press X Press Union 2 Inches

Product Description

The NIBCO PRESU2 is a 2-inch copper press x press union designed for joining and disconnecting sections of copper piping without soldering. The union configuration allows for future serviceability at the connection point, making it a practical choice for mechanical rooms, equipment drops, and any run where a break-apart fitting is required. Licensed plumbers and pipefitters install this fitting using a compatible press tool and appropriate copper press jaws. Its press-style end connections eliminate the need for open flame, reducing fire risk and speeding up installation in occupied or sensitive environments.

This union fitting is suited for residential and light commercial plumbing systems where copper press technology is specified. Typical applications include domestic hot and cold water distribution, hydronic heating supply and return lines, and closed-loop mechanical systems. The press x press configuration on both ends of the union accepts standard copper tubing sized at 2 inches, integrating cleanly into any copper press system from rough-in through final connection.

Key Features

• Press x press end connections on both sides — no soldering or open flame required

• 2-inch size fits standard copper tubing for main distribution and equipment connections
• Copper construction provides corrosion resistance suitable for potable water and hydronic applications

Installation Notes

Installation must be performed by a licensed plumber or pipefitter using a calibrated press tool fitted with the correct 2-inch copper press jaws. Shut off and depressurize the water or hydronic system and drain the line before making or breaking the union connection. Verify that tubing ends are clean, round, deburred, and marked to the correct insertion depth before pressing. Installation should comply with applicable local plumbing codes and the International Plumbing Code (IPC) where adopted.
