Mueller Industries W 01230 Copper Pipe Adapter 1/2x3/4 in

Product Description

The MUELLER INDUSTRIES W 01230 is a wrot copper pipe adapter designed to transition between a 1/2-inch copper sweat (C) connection and a 3/4-inch female threaded (F) connection using a solder joint end. Wrot copper construction provides high density and superior pressure integrity compared to cast fittings, making this adapter well suited for potable water, hydronic heating, and refrigeration piping systems. At 0.12 pounds, this compact fitting is a direct, no-compromise solution for licensed plumbers and HVAC technicians who need a reliable sweat-to-thread transition in tight spaces.

This adapter is used in residential and light commercial plumbing and mechanical systems wherever a copper sweat line must terminate into or connect from a female NPT-threaded port. Typical applications include water supply rough-in, hydronic piping, and refrigerant line sets requiring a threaded interface. The C x F configuration accepts a soldered male copper tube on the 1/2-inch end and threads onto a 3/4-inch female NPT fitting, valve, or equipment port on the opposite end.

Key Features

• Wrot copper body for high-density, leak-resistant pressure performance
• 1/2-inch sweat (C) inlet by 3/4-inch female NPT (F) outlet configuration
• Outside diameter: 5/8 inch x 3/4 inch
• Solder joint end connection for permanent, code-compliant installation
• Meets ASME B16.22, ASME B16.15, and NSF 61G standards for potable water service
• Lightweight at 0.12 pounds — easy to handle in confined rough-in areas

Compatibility

Designed as an OEM-style replacement or new-installation fitting for residential and light commercial copper piping systems requiring a 1/2-inch C x 3/4-inch F solder joint adapter.

Installation Notes

Installation is performed by a licensed plumber or qualified HVAC technician. Shut off and depressurize the water or fluid system completely before cutting or fitting any pipe. Clean and flux all mating copper surfaces before applying heat, and use lead-free solder in compliance with applicable local plumbing codes and NSF 61G requirements for potable water lines. Allow the joint to cool fully before restoring system pressure.
