Hailiang HL15-165-0100 Copper Coupling 7/8 in C X C

Product Description

The HAILIANG HL15-165-0100 is a 7/8-inch copper coupling designed for copper-to-copper sweat connections in refrigeration, HVAC, and plumbing piping systems. Configured as a R/S (rolled stop) fitting, it accepts standard C x C (copper by copper) solder-joint connections on both ends. The rolled stop positions the pipe consistently for uniform solder penetration and a reliable joint. This coupling is sold as a single unit and is installed by licensed HVAC technicians, refrigeration mechanics, and plumbers during new installations or repair work on copper line sets and distribution piping.

This fitting is suited for residential and light commercial applications where copper tubing is joined using sweat soldering methods. The C x C configuration makes it a standard workhorse fitting for refrigerant line repairs, domestic water distribution, and hydronic piping. It is appropriate wherever a 7/8-inch copper coupling with a rolled stop is required to restore or extend a copper piping run.

Key Features

• 7/8-inch size fits standard copper tubing of the same nominal diameter
• C x C connection type - both ends accept sweat solder joints
• R/S (rolled stop) configuration ensures consistent pipe seating and uniform joint quality
• Copper construction provides corrosion resistance suitable for refrigerant and water service
• Sold individually for single-fitting replacement or repair work

Compatibility

Designed as an OEM-style replacement fitting for 7/8-inch copper piping systems using sweat-solder C x C connections in HVAC, refrigeration, and plumbing applications.

Installation Notes

Installation should be performed by a licensed HVAC technician, refrigeration mechanic, or plumber in accordance with applicable local codes and ASME B16.22 standards for wrought copper fittings. Before soldering, evacuate or recover any refrigerant from the system and shut off water supply valves as applicable. Clean both the tube ends and fitting sockets with emery cloth and apply appropriate flux before heating. Do not overheat the fitting, as excess heat can damage the rolled stop or affect the integrity of the copper.
