The ELKHART PRODUCTS FA-1 is a 1-inch by 1-inch copper female adapter designed for solder-type connections in residential and commercial plumbing systems. It uses a copper-to-female (C x F) configuration, allowing a copper tube end to transition to a female threaded fitting. Part of the KLEENFIT product line, this adapter is cleaned and bagged at the factory to maintain flux-free surfaces and reduce prep time on the job. Licensed plumbers and pipefitters install this fitting during new construction, remodel work, and repair applications where a transition from soldered copper to female-threaded pipe is required.
This adapter is suited for water supply and distribution piping where soldered copper connections are standard practice. The KLEENFIT line is designed for plumbers who need fittings that arrive job-site ready without additional cleaning steps before soldering. At 1 inch by 1 inch, it fits standard nominal copper tubing and threaded pipe of the same size, making it a straightforward stock item for service vans and supply rooms alike.
Designed as an OEM-style replacement and standard-use fitting for 1-inch nominal copper plumbing systems requiring a transition from soldered copper tube to female-threaded connections.
Installation should be performed by a licensed plumber in accordance with the applicable local plumbing code and IPC guidelines. Shut off the water supply and relieve system pressure before cutting into any existing line. Clean and flux the copper tube end per standard soldering practice before applying heat; the KLEENFIT pre-cleaned surface does not eliminate the need for flux at the time of solder joint assembly. Allow the joint to cool fully before restoring water pressure and checking for leaks.
