Mueller Streamline W 01025 Reducing Coupling Copper

Product Description

The MUELLER STREAMLINE W 01025 is a copper reducing coupling designed to connect two copper tubing runs of different diameters in a single inline joint. It accepts a 1/2-inch nominal tube on one end and a 1/4-inch nominal tube on the other, with a C x C (sweat) end style on both sides. This fitting is intended for use in potable water, HVAC refrigerant piping, and other copper tubing systems where a step-down transition between tube sizes is required. It is installed by licensed plumbers and HVAC technicians as part of new construction or retrofit work.

This reducing coupling is suited for residential and light commercial applications where a smooth, soldered transition between 1/2-inch and 1/4-inch copper lines is needed. Common install scenarios include domestic water distribution systems, refrigerant line sets, and hydronic heating circuits. The domestic manufacturing designation makes it appropriate for projects subject to Buy American provisions or local code requirements specifying domestically produced fittings.

Key Features

• Reduces 1/2-inch nominal copper tube to 1/4-inch nominal copper tube in a single fitting
• C x C end style accepts standard sweat-solder connections on both ends
• Wrought copper construction provides reliable, corrosion-resistant joints
• Domestically manufactured for projects requiring domestic-origin fittings

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard 1/2-inch x 1/4-inch nominal copper tubing systems using C x C sweat connections.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician in accordance with applicable codes such as the IPC or IFGC. Shut off and depressurize the water or refrigerant system fully before cutting into any existing line. Clean and flux both tube ends thoroughly before soldering to ensure a leak-free joint. Do not use open-flame torches near combustible materials without proper shielding.
