The HAILIANG HL15-410-0222 is a copper fitting reducer designed for sweat-connection plumbing systems where a transition from a 1-1/4 inch line to a 1 inch line is required. The fitting end (FTG) on the larger side accepts a copper pipe OD directly, while the cup end (C) on the smaller side receives standard copper tube. Constructed from copper, this reducer handles the mechanical and pressure demands typical of residential and light commercial water distribution. Licensed plumbers and pipe fitters install this type of fitting when downsizing supply lines, branch connections, or riser transitions in copper piping systems.
This reducer is suited for residential and light commercial plumbing applications including domestic hot and cold water supply, hydronic heating distribution lines, and branch reductions within copper piping systems. The FTG x C end configuration allows it to be soldered directly into a copper pipe run without an additional coupling, making it a practical choice for tight installation spaces or in-line reductions.
Designed as an OEM-style replacement and standard fitting for copper sweat piping systems using 1-1/4 inch to 1 inch nominal pipe size reductions.
Installation should be performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off the water supply and fully depressurize and drain the line before cutting and fitting. Clean and flux all mating surfaces before soldering, and use lead-free solder where required for potable water applications. Allow the joint to cool completely before restoring water pressure.
