Brass Flare Short Nut – High-Precision Flare Fitting Nut for Secure, Leak-Proof Connections

The Brass Flare Short Nut is an essential flare fitting component designed to fasten flare connections with compact dimensions that save space while ensuring maximum reliability. Manufactured from premium forged brass alloy (CW617N/C37700), this short nut offers exceptional mechanical strength, corrosion resistance, and durability under harsh operating conditions.

Key Features & Advantages:

• Material Quality: Made from high-grade forged brass, delivering excellent corrosion resistance and durability in HVAC, refrigeration, gas, and plumbing systems

• Compact Design: Shorter length than standard flare nuts, ideal for tight or confined spaces without sacrificing sealing performance

• Thread Standard: SAE flare threads, precision-cut for a smooth and secure fit; customizable with NPT, BSP, BSPT, or metric threads on request

• Surface Finish Options: Natural brass finish or enhanced corrosion protection with optional nickel or chrome plating

• Pressure Capacity: Rated for medium to high-pressure applications, generally up to 800 PSI depending on size

• Temperature Range: Functional in temperatures from -65°F (-53°C) to +250°F (121°C), suitable for a wide variety of environmental conditions

• Manufacturing Precision: CNC machined with tight tolerances for consistent threading and flawless fit, ensuring leak-proof connections every time

• Seal Type: Metal-to-metal seal formed by the flare fitting, eliminating the need for additional gaskets or O-rings
