Nibco PRESU112 Copper Press Union 1-1/2 Inches

Product Description

The NIBCO PRESU112 is a 1-1/2 inch copper press x press union designed for joining copper tubing in pressurized water and hydronic systems. This union allows technicians to disconnect and reconnect a piping section without cutting pipe, making it a practical choice for service access points and future maintenance locations. The press-style end connections eliminate open-flame soldering, speeding up installation and reducing fire risk in occupied structures. Licensed plumbers and pipefitters are the primary installers of this fitting type.

The PRESU112 is suited for residential and light commercial plumbing, hydronic heating, and radiant systems where 1-1/2 inch copper main lines require a serviceable union connection. Press fittings are commonly used in mechanical rooms, boiler rooms, and retrofit applications where torch work is restricted or impractical. This fitting is installed inline on straight copper tube runs where future disassembly may be required.

Key Features

• Press x press end connections eliminate the need for open-flame soldering
• 1-1/2 inch connection size suits main distribution lines in residential and light commercial systems
• Union design allows the piping section to be disconnected and reassembled for service access
• Copper construction provides corrosion resistance suitable for potable water and hydronic fluid service

Compatibility

Designed as an OEM-style replacement and standard-service fitting for 1-1/2 inch copper tube press piping systems in plumbing and hydronic heating applications.

Installation Notes

Installation requires a manufacturer-approved press tool with the correct jaw size for 1-1/2 inch press fittings. Shut off and depressurize the system completely before disassembling or pressing any connection. Work must comply with applicable local plumbing codes and ASTM standards for copper press systems. Verify that the press ring or sleeve is fully seated before actuating the press tool to ensure a leak-free joint.
