Mueller Industries 15757 Copper Pipe Reducer 1/2 X 3/8 C X C

Product Description

The MUELLER INDUSTRIES 15757 is a wrot copper pipe reducer fitting designed to transition between 1/2-inch and 3/8-inch copper tubing using sweat (C x C) end connections. Wrot copper construction provides reliable pressure integrity and consistent wall thickness, making this reducer suitable for potable water, HVAC refrigerant piping, and hydronic systems. The fitting is sized at 5/8 inch x 1/2 inch outside diameter. Licensed plumbers and HVAC technicians use this fitting when stepping down tubing size within a copper piping system.

This reducer is appropriate for residential and light commercial plumbing and HVAC applications where a sweat-soldered size transition is required. Typical uses include domestic water supply lines, hydronic heating loops, and refrigerant line sets where tubing diameters must be reduced between equipment connections. The C x C end configuration requires soldering on both ends, making it a standard choice for copper-to-copper installations.

Key Features

• Wrot copper construction for consistent wall thickness and reliable joint integrity
• C x C (sweat) end connections on both ends for standard solder installation
• Reduces from 1/2-inch to 3/8-inch tubing (5/8 inch x 1/2 inch outside diameter)
• Compatible with potable water, HVAC, and hydronic piping applications
• Sold in a package quantity of 5 fittings

Compatibility

Designed as an OEM-style sweat-solder reducer for standard copper tubing systems requiring a 1/2-inch to 3/8-inch transition with C x C end connections.

Installation Notes

Installation is performed by a licensed plumber or HVAC technician. Shut off the water supply or isolate the refrigerant circuit and relieve system pressure before beginning work. Clean and flux both the fitting socket and tubing ends thoroughly before applying heat; proper surface preparation is critical to a leak-free solder joint. Follow applicable local plumbing codes and IFGC or IPC guidelines for material and installation requirements.
