1-1/2 inch Copper Union Copper x Copper

Contractor-Grade 1-1/2 inch Lead-Free Copper Union – Engineered for System Integrity

The 1-1/2 inch Lead-Free Copper Union is precision-engineered to enable disconnection and reassembly of copper pipe systems without compromising joint integrity. Ideal for high-performance potable water systems, this union is constructed to meet rigorous job site demands, facilitating maintenance, system upgrades, and retrofit applications where soldered joints must remain serviceable.

Advantages of a Copper Union in Professional Installations

• ✅ Lead-Free Copper Alloy – Manufactured to comply with NSF/ANSI 61 and NSF 372 standards for potable water safety in accordance with U.S. plumbing codes.
• ✅ True Union Design – Enables line disassembly at a specific connection point without cutting pipe, enhancing serviceability and reducing downtime.
• ✅ Machined Seat Faces – Provides a robust sealing surface for gasket or metal-to-metal compression, minimizing risk of leakage at pressure-bearing joints.
• ✅ Heavy-Duty Nut & Thread – Designed to maintain clamping strength under repeated thermal cycling and vibration.
• ✅ Compatible with Type L and M Copper Tubing – Ensures seamless integration into standard residential and light-commercial distribution systems.

Installation Considerations

To ensure system integrity, copper unions should be installed with appropriate flux and solder at the sweat connections, while the union nut is torqued using standard hand tools. For pressure systems, it is recommended to inspect sealing surfaces prior to installation and pressure test the system after assembly. Pipe ends must be clean, dry, and properly deburred before joining.
