Dakota Sourcing 12648 Short Flare Nut 5/8 Inch Lead Free

Product Description

The DAKOTA SOURCING 12648 is a 5/8-inch short flare nut machined from bar stock and manufactured lead free. This fitting is used to secure flared tubing connections in refrigeration, HVAC, and plumbing systems where a compact nut profile is required. The lead-free construction meets current regulatory requirements for potable water and refrigerant piping applications. Plumbers, HVAC technicians, and refrigeration mechanics use this type of nut when making or remaking flared tube joints in tight spaces where a standard-length nut would be difficult to seat or torque.

The 12648 is suited for residential and light commercial service work involving 5/8-inch flare fittings. Its short bar stock body is appropriate for copper tubing connections commonly found in refrigerant line sets, domestic water supply lines, and gas piping assemblies that call for a flare-style joint. The compact length is especially useful in panel or cabinet installations where clearance is limited.

Key Features

• 5/8-inch flare thread size for standard flared tubing connections
• Short body profile for use in confined or low-clearance installations
• Bar stock construction for consistent dimensional accuracy
• Lead-free material meets regulatory requirements for potable water and refrigerant applications

Compatibility

Designed as an OEM-style replacement or service fitting for 5/8-inch flare connections in residential and commercial HVAC, refrigeration, and plumbing systems.

Installation Notes

Installation of flare nuts is typically performed by licensed HVAC technicians or plumbers depending on the application. Always depressurize and evacuate the line before disconnecting or replacing any flare fitting. Inspect the flare seat on the tubing for cracks or deformation before threading on the nut. Follow applicable local codes, including IFGC for gas piping and IPC for water supply, when selecting fitting types and materials.
