Hailiang HL15-172-0215 Copper Repair Coupling 1-1/4 in

Product Description

The HAILIANG HL15-172-0215 is a 1-1/4 inch copper repair coupling with no internal stop, designed for joining or splicing copper tubing in plumbing systems. The absence of an internal stop allows the fitting to slide fully over the pipe, making it the correct choice for in-line repairs where one end of the tubing cannot be moved. It uses a standard C x C (copper sweat) connection on both ends, requiring solder and a torch for a pressure-tight joint. Plumbers and pipefitters use this type of coupling for repair work on residential and light commercial water supply lines, as well as hydronic heating systems.

This coupling is suited for repair applications on 1-1/4 inch copper tubing where a standard stop coupling cannot be used due to fixed pipe positions. Typical install scenarios include pinhole leak repairs, freeze damage repairs, and splice work on existing supply or return lines. The C x C end connections are compatible with standard hard-drawn and soft copper tubing of the same nominal size. No special adapters or transition fittings are required when joining copper to copper within the same line.

Key Features

• No internal stop allows the coupling to slide freely over tubing for in-line repairs
• C x C sweat connections on both ends for a reliable soldered joint
• 1-1/4 inch nominal size with 1-3/8 inch OD fits standard copper tubing
• Full copper construction provides corrosion resistance suitable for potable water and hydronic systems
• Repair-style design eliminates the need to cut additional pipe length to accommodate a stop

Compatibility

Designed as a direct-sweat repair fitting for 1-1/4 inch nominal copper tubing in standard plumbing and hydronic piping applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC requirements. Shut off the water supply and fully drain the affected line before cutting or soldering. Clean both pipe ends and the interior of the fitting with emery cloth and flux before applying heat and solder. Do not apply flame directly to the fitting body for an extended period, as overheating can weaken the copper and cause solder voids.
