Hailiang HLG15-657-0295 Copper Union 1-1/2 Inch C X C

Product Description

The HAILIANG HLG15-657-0295 is a 1-1/2 inch copper union with copper-to-copper (C x C) sweat connections, designed for use in residential and commercial plumbing systems. Unions allow sections of copper pipe to be disconnected and reconnected without cutting, making them essential for serviceable connections at water heaters, pumps, and shutoff assemblies. The fitting is machined from copper with an outside diameter of 1-5/8 inches, consistent with standard 1-1/2 inch nominal pipe sizing. Licensed plumbers and pipefitters specify copper unions where future access or component replacement is anticipated in the system layout.

This union is suited for potable water supply lines, hydronic heating loops, and general plumbing distribution systems where a removable, leak-tight joint is required. The C x C end configuration accepts standard 1-1/2 inch copper tubing soldered with lead-free solder per current plumbing code requirements. It is appropriate for both new construction rough-in and retrofit service work where an existing threaded or soldered connection must be broken and re-established cleanly.

Key Features

• 1-1/2 inch nominal size with C x C sweat end connections for direct copper tubing integration
• Copper construction provides corrosion resistance in potable water and hydronic applications
• Outside diameter of 1-5/8 inches matches standard nominal 1-1/2 inch copper pipe fitment
• Union design allows future disconnection without cutting pipe, simplifying equipment service
• Compatible with lead-free solder per IPC and local plumbing code requirements

Compatibility

Designed as a standard OEM-style replacement or new-installation copper union for 1-1/2 inch nominal copper pipe systems using sweat (solder) connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local IPC or applicable plumbing codes. Shut off the water supply and depressurize and drain the line fully before cutting or soldering. Use lead-free solder and appropriate flux rated for potable water service when making sweat connections. Allow all joints to cool completely before restoring system pressure and inspecting for leaks.
