Brass Flare Nuts are specialized fasteners used in flared fitting assemblies to secure the flared end of tubing—creating a leak-proof, pressure-resistant joint without the need for soldering. Engineered from high-quality brass (such as UNS CA-360), these nuts combine durability, corrosion resistance, and a refined appearance, making them ideal for critical HVAC, refrigeration, and gas distribution applications. As one of India’s leading manufacturers and suppliers, we produce a wide range of Brass Flare Nuts at our advanced facility in Jamnagar. Our products are trusted worldwide for their precision, reliability, and superior quality.
Brass Flare Nuts Key Features
Material & Finish:
Made from premium brass, these flare nuts offer natural corrosion resistance and a warm, attractive finish. Their robust construction is suitable for use with liquefied petroleum gases, natural gas, and other fluids.Design & Function:
Designed to mate with a 45° flared tubing end, the nut’s precision-machined hex profile allows for secure tightening with standard tools. This metal-to-metal contact between the flared tube and fitting provides a durable, leak-tight seal even under moderate to high pressures.Standards & Performance:
Often conforming to SAE standards (such as SAE J513 for refrigeration fittings), brass flare nuts are typically rated for pressures up to 700 psig and can operate efficiently over a temperature range from –65°F to +250°F. Their design also offers good vibration resistance, which is critical for many industrial applications.Versatility:
Available in various sizes and thread specifications, these nuts are tailored to match corresponding flared tubing diameters—from small-diameter lines to larger HVAC and refrigeration applications.
