Hailiang HL15-105-0520 Copper Female Adapter 2.5in C X F

Product Description

The HAILIANG HL15-105-0520 is a 2.5-inch copper female adapter with a C x F (copper sweat by female threaded) end configuration. This fitting transitions a copper sweat connection to a female threaded joint, allowing a soldered copper pipe run to terminate at or connect to a threaded fitting or valve body. It is used in potable water supply, hydronic heating, and general plumbing distribution systems. Licensed plumbers install this adapter during new construction, remodel work, and service repairs where a copper-to-threaded transition is required. The copper construction delivers reliable corrosion resistance and long service life in both hot and cold water applications.

This adapter is suited for residential and light commercial plumbing installations. It fits 2.5-inch nominal copper pipe with an OD of 2-5/8 inches on the sweat end and accepts a 2.5-inch female thread on the opposite end. Typical applications include connecting copper distribution mains to threaded valves, unions, flanges, or equipment inlets. It is commonly installed at mechanical room headers, water heater connections, and main shutoff valve assemblies where a copper run transitions to threaded iron or bronze components.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off the water supply and depressurize and drain the line before soldering. Clean and flux the copper tube end and fitting socket thoroughly before applying heat to ensure a proper solder joint. Do not apply thread sealant or PTFE tape to the female threaded end until the soldered joint has fully cooled and been inspected.
