Hailiang HL15-105-0159 Copper Female Adapter 1x3/4 Cxf

Product Description

The HAILIANG HL15-105-0159 is a copper female adapter fitting designed to transition from a 1-inch copper sweat connection to a 3/4-inch female threaded connection (C x F). Manufactured from copper, this adapter is used to connect copper tubing to female-threaded components in potable water and hydronic piping systems. The sweat-by-female configuration allows a licensed plumber to solder the copper end directly to tubing while threading the female end onto a male-threaded valve, nipple, or equipment fitting. It is a standard trade fitting used in residential and light commercial plumbing installations.

This adapter is suited for residential and light commercial plumbing applications where a reduction and thread transition are needed in a single fitting. Typical install scenarios include connecting copper supply lines to threaded valves, water heaters, pumps, or manifold ports where the upstream tubing is 1-inch copper and the downstream connection is a 3/4-inch male-threaded component. The C x F configuration eliminates the need for a separate reducing coupling and threaded fitting in tight spaces.

Key Features

• Copper construction provides corrosion resistance and long service life in potable water systems
• 1-inch sweat (C) inlet transitions to 3/4-inch female threaded (F) outlet in a single fitting
• C x F configuration compatible with standard sweat soldering and NPT threaded connections
• Compact design reduces the number of fittings needed at transition points
• Suitable for use in residential and light commercial plumbing piping systems

Compatibility

Designed as an OEM-style replacement and standard-use copper female adapter for residential and light commercial plumbing systems requiring a 1-inch copper sweat to 3/4-inch female threaded transition.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure before soldering or making any threaded connections. The sweat end requires proper flux application and lead-free solder per applicable codes before heating. Apply thread sealant or PTFE tape to the male-threaded component before engaging the female threads to ensure a leak-free connection.
