Mueller Streamline ADP00426 Copper Adapter Cxf

Product Description

The MUELLER STREAMLINE ADP00426 is a wrot copper adapter fitting designed to transition between a copper sweat connection and a female threaded pipe connection. Sized at 1.13 inches by 1 inch, this CxF (Female C x FPT) adapter is a standard component in copper potable water, HVAC, and hydronic piping systems. It connects a copper tube end, soldered in place, to a female National Pipe Thread port on valves, equipment, or other threaded fittings. Licensed plumbers and HVAC technicians install this fitting during new construction and retrofit work wherever a threaded-to-sweat transition is required.

This adapter is suited for residential and light commercial plumbing and HVAC applications. It is commonly installed at equipment connections, shut-off valve ports, and distribution manifolds where copper tubing terminates at a female-threaded component. The 1.13 x 1 inch size accommodates standard copper tube outer diameter on the sweat end and a 1-inch FPT on the threaded end. It carries the WC-402 product reference designation used in the Streamline fittings catalog.

Installation Notes

Installation is performed by a licensed plumber or HVAC technician. Shut off water supply and depressurize the line before soldering.

Do not use open flame near combustible materials without appropriate shielding, and allow the fitting to cool completely before pressurizing the system.
