The LIZIFEQZ 1/2" Brass Flare Nut is a precision-engineered component designed for high-flow applications requiring larger diameter copper tubing. Ideal for main supply lines, commercial HVAC systems, and industrial refrigeration, these 1/2 inch SAE 45° flare nuts deliver reliable, leak-proof connections in demanding environments.
Crafted from high-quality solid brass, each flare nut offers exceptional corrosion resistance, high-temperature ductility, and low magnetic permeability. The material withstands harsh environments, making it ideal for applications ranging from main gas lines to commercial water systems.
The SAE 45° flare design creates a robust metal-to-metal seal when tightened against a flared copper tube end. This sealing method provides several advantages over welded or soldered connections:
No Welding Required: Quick, clean installation without special equipment
Reusable: Easily disassemble and reconnect without replacing components
Temperature Resistant: Maintains seal integrity from -65°F to +250°F
High Pressure Capable: Withstands up to 1200 PSI working pressure
Leak-Proof: Metal-to-metal seal eliminates need for sealants or gaskets
These versatile fittings are perfect for countless applications:
Main Supply Lines: Natural gas, propane, and water main connections
Commercial HVAC: Large air conditioning units, heat pumps, and chillers
Industrial Refrigeration: Cold storage, process cooling, and food processing
Hydronic Heating: Boiler connections and radiant heating systems
Marine & Industrial: Fuel lines and cooling systems for heavy equipment
Each set includes 10 brass flare nuts, providing ample supply for multiple connections or replacements.
