Hailiang HLG15-657-0215 Copper Union 1-1/4 in Cxc

Product Description

The HAILIANG HLG15-657-0215 is a 1-1/4 inch copper union designed for sweat (CxC) copper tubing connections in residential and commercial plumbing systems. This union allows technicians to join or disconnect two sections of copper pipe without cutting, making it a critical fitting for service points, equipment connections, and future maintenance access. Constructed from copper, it delivers reliable, corrosion-resistant performance in potable water, hydronic heating, and general plumbing distribution lines. The 1-3/8 inch OD size is consistent with standard 1-1/4 inch nominal copper tube dimensions.

This union fits into residential and light commercial plumbing installations where soldered copper piping is used. Typical applications include water supply lines, boiler and hydronic piping, and mechanical room connections where periodic disassembly may be required. It is installed by licensed plumbers working with Type K, L, or M copper tubing in sweat-fit configurations.

Key Features

• 1-1/4 inch nominal size with 1-3/8 inch OD — matches standard copper tubing dimensions
• CxC (copper by copper) sweat connection on both ends
• Full copper construction for corrosion resistance in wet plumbing environments
• Union design allows pipe disconnection without cutting for serviceability
• Suitable for potable water, hydronic, and general plumbing distribution applications

Compatibility

Designed as an OEM-style replacement and standard-fit union for 1-1/4 inch nominal copper sweat piping systems in residential and commercial plumbing applications.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC and local plumbing code requirements. Shut off the water supply and depressurize and drain the line fully before beginning any soldering work. Clean and flux all mating surfaces before applying heat to ensure a leak-free solder joint. Do not overtighten the union nut after soldering the end connections, as copper is subject to deformation under excessive mechanical force.
