The DAKOTA SOURCING 12646 is a 1/4-inch flare short bar stock nut designed for use in refrigerant, fuel gas, and fluid line connections where a flare fitting is required. This lead-free nut is machined from bar stock for consistent thread integrity and dimensional accuracy. Its compact short-body profile suits tight-clearance installations where a standard-length flare nut would not seat properly. Licensed HVAC technicians and plumbers install this type of fitting as part of flare connection assemblies on copper tubing systems.
This short flare nut is suited for residential and light commercial applications involving 1/4-inch OD copper tubing flare connections. Common install scenarios include refrigerant line sets, fuel gas distribution systems, and water supply connections where flare-type fittings are specified. The lead-free construction meets requirements for potable water service as well as refrigerant and gas applications where lead content is restricted by code.
Designed as an OEM-style replacement or service fitting for 1/4-inch flare connection assemblies in residential and commercial HVAC, plumbing, and gas piping systems.
Installation is typically performed by a licensed HVAC technician or plumber. Before service, de-energize the system and isolate or recover any refrigerant or shut off gas and water supply as applicable per local code. Use a properly sized flare nut wrench to avoid rounding the fitting body. Follow applicable sections of the International Fuel Gas Code, International Plumbing Code, or system manufacturer torque guidance when making flare connections.
