Why Choose This Brass Flare Fitting?

• Corrosion-Resistant Brass Construction: Built from solid brass that naturally resists oxidation, moisture, and mild chemical exposure — ensuring long-term, stable performance even in humid or demanding environments. Reduces the need for frequent replacements and lowers long-term maintenance costs.
• Reliable Leak-Free Seal: Precision-machined ferrule and threaded structure creates a firm, tight bite on tubing without welding. Effectively prevents leakage of liquid, gas, or oil, protecting your system and property from costly connection failures.
• Multiple Sizes for Versatile Use: One purchase covers a wide range of outer diameter tubing — fits copper, aluminum, and soft plastic lines across residential plumbing, refrigeration, pneumatic systems, gas piping, potable water, and fuel line applications.
• High Pressure & Temperature Stability: Brass body withstands significant working pressure and wide temperature fluctuations, performing reliably in both cold and hot fluid transfer systems across varied application conditions.
• Tool-Friendly Installation: Hexagonal anti-slip matte brass body fits standard household wrenches perfectly. No professional skills required — easy to tighten quickly, saving installation time and labor costs.
