Hailiang HL15-165-0215 Copper Coupling 1-1/4 in Cxc

Product Description

The HAILIANG HL15-165-0215 is a 1-1/4 inch copper coupling with roll stop, designed for copper-to-copper (CxC) sweat connections in plumbing and mechanical piping systems. The roll stop is an internal shoulder that limits pipe insertion depth, ensuring consistent joint positioning and reliable solder joints. With a 1-3/8 inch OD and full copper construction, this coupling meets standard dimensional requirements for residential and light commercial plumbing installations. It is a direct-connect fitting for extending or joining copper water lines and is installed by licensed plumbers and pipefitters.

This coupling is suited for potable water supply lines, hydronic heating systems, and general-purpose copper piping where a CxC sweat fitting is required. The 1-1/4 inch nominal size is common in main distribution lines, branch mains, and recirculation loops in both residential and light commercial construction. The roll stop feature makes it particularly well-suited for production plumbing work where uniform joint depth speeds up installation and reduces the risk of incomplete insertion before soldering.

Key Features

• Roll stop internal shoulder ensures consistent pipe insertion depth for reliable solder joints
• Copper construction provides corrosion resistance and compatibility with potable water systems
• CxC (sweat x sweat) end connections suit standard torch-and-solder installation methods
• 1-1/4 inch nominal size with 1-3/8 inch OD fits standard copper tube and fittings
• Suitable for use in plumbing, hydronic, and mechanical piping applications

Compatibility

Designed as an OEM-style replacement and standard-use fitting for 1-1/4 inch nominal copper pipe systems requiring CxC sweat connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing codes. Shut off and drain the water supply before cutting into any existing line. Clean pipe ends and fitting sockets thoroughly with emery cloth and apply flux before soldering to ensure a leak-free joint. Do not over-heat the fitting during soldering, as excessive heat can damage the copper or burn off flux before the solder flows properly.
