The ELKHART PRODUCTS WP4-2-04 is a 1/4 inch copper male street adapter designed for solder-joint copper tubing systems. It features a FTG x M connection, allowing it to transition between a fitting-end socket and a male threaded end within a copper piping assembly. This fitting is part of the WROT copper product line, which is manufactured from wrought copper for consistent wall thickness and reliable soldering performance. Licensed plumbers and pipefitters install this type of adapter where a copper run must terminate or transition to a male threaded connection in tight residential or light commercial applications.
This adapter is suited for use in residential and light commercial plumbing systems wherever a 1/4 inch copper line requires a male-threaded termination point. The FTG end sweats directly onto copper tubing, while the male-threaded end connects to a corresponding female-threaded fitting or valve. Its compact size makes it practical in confined spaces such as appliance supply lines, refrigeration piping, or instrument connections where 1/4 inch copper tubing is standard.
Designed as an OEM-style replacement or new-installation fitting for 1/4 inch copper tubing systems using solder-joint connections in residential and light commercial plumbing applications.
Installation is performed by a licensed plumber or qualified pipefitter. Shut off the water supply and depressurize the line before soldering. Clean all mating surfaces with emery cloth and apply flux before sweating the FTG end onto the copper tubing per standard soldering practice and applicable plumbing codes. Use lead-free solder where required by local code for potable water systems.
