The DAKOTA SOURCING 13130 is a copper fitting reducer designed to transition between two different tube sizes in a sweat-connect piping system. The inlet end accepts a 3/4-inch OD fitting-style (FTG) connection and reduces to a 5/8-inch OD copper (C) sweat outlet. This fitting is sized for tubing with a 5/8-inch OD inlet and 1/2-inch OD outlet when measured at the tubing dimension. Plumbers and HVAC technicians use this reducer to step down refrigerant or fluid lines where a size change is required without adding an inline coupling and separate reducer.
This fitting is suited for residential and light commercial plumbing and HVAC refrigerant piping applications where copper sweat fittings are specified. The FTG inlet allows it to slide directly over the end of a male fitting, making it useful for tight or back-to-back fitting connections. Installers working on split systems, chilled water lines, or domestic water supply runs will find this reducer useful wherever a 3/4-inch to 1/2-inch tube size transition is needed.
Designed as an OEM-style replacement and general-use copper sweat reducer for residential and light commercial plumbing and HVAC refrigerant piping systems that use standard copper tubing and fittings.
Installation should be performed by a licensed plumber or HVAC technician in accordance with applicable local codes, the International Plumbing Code (IPC), or ASHRAE guidelines where refrigerant lines are involved. Shut off and recover refrigerant or depressurize and drain the fluid system before cutting into any line. Clean and deburr tubing ends and flux all mating surfaces before soldering or brazing. Do not apply flame directly to the fitting socket for extended periods, as overheating can damage the fitting or contaminate the line set.
