Mueller Industries W 01279 Copper Pipe Adapter 1-1/2 in

Product Description

The MUELLER INDUSTRIES W 01279 is a wrot copper pipe adapter designed for sweat-solder plumbing connections. It transitions between a copper-to-copper (C) male socket end and a female threaded (F) end, making it a standard fitting for connecting copper tubing runs to threaded female fittings or valves. The fitting measures 1-1/2 inches in size with an outside diameter of 1-5/8 inches on the socket end and 1-1/2 inches on the female threaded end. Wrot copper construction provides the density and pressure performance that residential and commercial plumbing systems demand. Licensed plumbers and pipefitters are the primary installers of this fitting.

This adapter is suited for residential and light commercial plumbing applications where a copper sweat connection must terminate into a female NPT threaded port. Typical scenarios include connecting copper supply lines to threaded valves, manifolds, or equipment inlets. The solder joint end conforms to established copper fitting standards, making it a reliable choice for potable water systems, hydronic heating loops, and general plumbing distribution piping where a C x F transition is required.

Key Features

• Wrot copper construction for consistent wall thickness and reliable solder joints
• C x F end connection — copper sweat socket on one end, female NPT thread on the other
• 1-1/2 inch fitting size with 1-5/8 x 1-1/2 inch outside diameter profile
• Meets ASME B16.22 and ASME B16.18 dimensional standards for wrought and cast copper fittings
• NSF 61G listed for use in potable water systems
• Complies with ASME B1.20.1 for pipe thread form on the female threaded end

Compatibility

Designed as an OEM-style replacement and standard-use fitting for 1-1/2 inch copper plumbing systems requiring a C x F solder joint adapter in residential and commercial installations.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and fully drain the line before cutting or soldering. Clean all mating surfaces with emery cloth and apply flux before soldering; heat the fitting body evenly and allow solder to draw into the joint by capillary action. The female threaded end requires the use of thread sealant tape or compound rated for potable water service before assembling to the mating male thread.
