Brass Flare Female Connector
Brass Flare Female Connector
033-DFFC
The Brass Flare Female Connector is a precision-engineered fitting designed to connect a flared tube to a male-threaded port in HVAC, refrigeration, gas, and fluid transfer systems. Manufactured from high-quality forged brass alloys such as CW617N or C37700, this connector provides excellent durability, corrosion resistance, and long service life.
The flare connection creates a secure metal-to-metal seal, ensuring leak-free performance even in high-pressure and high-temperature environments. Precision-machined threads allow easy installation and reliable sealing without the need for additional sealing compounds.
Brass Flare Female Connectors are widely used in air conditioning systems, refrigeration equipment, gas pipelines, hydraulic machinery, and industrial fluid control systems, where dependable tube-to-port connections are required.
