Dakota Sourcing 12697 Swivel Nut Union 3/8 Inch Flare

Product Description

The DAKOTA SOURCING 12697 is a 3/8 inch flare swivel nut union designed to connect two flare fittings in refrigerant, fuel gas, or similar tubing systems. The swivel nut design allows the fitting to rotate during tightening, reducing the chance of twisting or kinking the connected tubing. This union is lead free, making it suitable for installations where lead-free compliance is required. Licensed HVAC technicians, plumbers, and gas fitters commonly install this type of fitting during system assembly or service work.

This swivel nut union is suited for residential and light commercial applications where a reliable flare-to-flare connection is needed. Typical use cases include refrigerant line connections, natural gas or LP gas supply lines, and fuel oil tubing assemblies. The 3/8 inch flare size is a common dimension in these systems, making this union a practical service and replacement part for field technicians.

Key Features

• 3/8 inch flare x flare connection on both ends

Compatibility

Installation Notes

Installation should be performed by a licensed HVAC technician, plumber, or gas fitter in accordance with applicable local codes, including IFGC and IPC requirements where relevant. Shut off and depressurize the system completely before disconnecting or connecting any fittings. Use two wrenches when tightening flare connections to prevent tubing from rotating. Do not overtighten flare fittings, as this can damage the flare seat and cause leaks.
