Hailiang HL15-172-0100 Copper Repair Coupling 3/4 in

Product Description

The HAILIANG HL15-172-0100 is a 3/4-inch copper repair coupling without a stop, designed for sweat-connect (C x C) copper pipe repairs in residential and commercial plumbing systems. The absence of a stop allows the fitting to slide freely along the pipe, making it the correct choice when joining two pipe ends in a mid-run repair where a standard coupling with a center stop cannot be seated. Constructed from copper, this coupling provides reliable corrosion resistance and long service life in potable water and hydronic applications. Licensed plumbers and pipefitters install this fitting using standard soldering techniques.

This repair coupling is used in situations where a damaged section of copper pipe must be cut out and replaced with a short segment, requiring two slide-over couplings to complete the joint. It fits 3/4-inch nominal copper pipe and is well suited for residential water supply lines, commercial plumbing rough-in work, and in-wall or under-slab repairs where clearance is limited and a stop-type coupling cannot be used.

Key Features

• No center stop allows the coupling to slide freely for mid-run pipe repair applications
• C x C (copper sweat) connection on both ends for standard solder joining
• 3/4-inch nominal pipe size with 7/8-inch OD
• Full copper construction for corrosion resistance and compatibility with potable water systems
• OEM-style form factor matches standard copper fitting dimensions for straightforward replacement

Compatibility

Designed as a repair-style sweat coupling for use with standard 3/4-inch nominal copper pipe (Type K, L, or M) in plumbing systems requiring a slip-style, stop-free connection.

Installation Notes

Installation must be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and fully drain the affected line before cutting out the damaged section. Clean and flux all pipe ends and fitting sockets before soldering, and use lead-free solder where required for potable water service. Do not apply heat to the fitting while water or moisture remains in the line.
