The HAILIANG HL15-105-0150 is a 1-inch copper female adapter configured in a C x F (sweat x female threaded) end pattern. This fitting connects a copper sweat line to a female threaded port, making it a standard transition piece in residential and light commercial plumbing systems. Fabricated from copper, it delivers reliable corrosion resistance and long service life in potable water and hydronic applications. Licensed plumbers and experienced pipefitters install this adapter as part of new construction roughing, fixture connections, and repair work where a threaded female termination is required on a copper run.
This adapter is suited for use in residential water supply lines, commercial plumbing distribution systems, and hydronic heating piping. The 1-inch nominal size covers a broad range of branch and main-line connection scenarios. The sweat end is soldered directly onto copper tubing while the female threaded end accepts a standard male-threaded fitting, valve, or fixture supply connection. It is commonly installed at fixture shutoff valve transitions and at equipment connection points throughout the system.
Designed as an OEM-style replacement or new-install fitting for 1-inch copper plumbing systems requiring a sweat-to-female-thread transition.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Shut off the water supply and fully drain the line before soldering. Clean and flux the copper tube end and fitting socket thoroughly prior to applying heat. Do not apply flame directly to the threaded portion of the fitting, as excessive heat can damage thread integrity.
