Brass Flare Union
The Brass Flare Union is a precision-engineered fitting designed to securely connect two flared tubes, ensuring a reliable and leak-proof joint. Manufactured from premium forged brass such as CW617N or C37700, this fitting provides excellent mechanical strength, corrosion resistance, and long-term durability.
Designed for demanding fluid and gas systems, brass flare unions create a metal-to-metal 45° flare seal, eliminating the need for sealants or thread tapes. This ensures dependable sealing performance even in high-pressure and temperature-sensitive environments.
These fittings are widely used in HVAC systems, refrigeration equipment, hydraulic lines, gas distribution systems, and industrial fluid handling applications. With precision machining and strict quality control, brass flare unions deliver consistent performance and easy installation across various industries worldwide.
