1/2 inch Brass Flared Adapter OD Flare x Male

1/2 inch Brass Flare x MIP Adapter – Lead-Free Fitting for Gas and Water Applications

The 1/2 inch Brass Flared Adapter is a transition fitting used to connect a flared copper or aluminum tube to a female NPT-threaded port. This fitting features a 1/2 inch flare connection on one end and a 1/2 inch male iron pipe (MIP) thread on the other, allowing for secure mechanical connections in systems that require vibration resistance, high-pressure performance, or reusability without soldering.

Constructed from lead-free brass (per NSF/ANSI 372), this adapter is compliant with potable water system requirements and is also suitable for fuel gas, refrigeration, and hydraulic lines. It conforms to SAE J512 and ASME B1.20.1 standards for dimension and threading.

Product Features

• ✅ Connection Type: 1/2 inch Flare x 1/2 inch Male NPT (National Pipe Taper)
• ✅ Material: Lead-free brass, corrosion-resistant and rated for use in potable and fuel systems
• ✅ Thread Standard: ASME B1.20.1 (NPT); flare end per SAE J512
• ✅ Operating Pressure: Typically rated up to 200–600 PSI (dependent on system type and installation method)
• ✅ Temperature Range: -65°F to 250°F in fluid or gas systems

Application Scope

Commonly used in both residential and commercial installations for water service, LP/natural gas lines, HVAC refrigerant loops, and hydraulic systems. Flared connections are ideal where disassembly and reassembly are required without disturbing the piping system or introducing flame into the workspace.

Installation Notes

For proper installation, ensure the flared tubing end is clean and properly formed to match the flare seat. Use a flare nut to secure the tubing against the adapter’s machined surface. Do not use thread sealant on the flare connection. For the male NPT side, apply PTFE tape or thread sealant as specified by system requirements. Torque must be applied within recommended limits to avoid damaging the flare seat or distorting the fitting.

Code Compliance

This fitting complies with the Safe Drinking Water Act (SDWA) for use in potable systems and is listed under NSF/ANSI 61 and 372. It is also approved for use in fuel gas systems when installed according to NFPA 54 and local code requirements.
