Simply flare the tube end, slip the nut over, and tighten. A commercial refrigeration flare nut set that makes main line maintenance simple and cost-effective.

Description

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.
