Brass Flare Female Connector
Brass Flare Female Connector
033-DFFC
In HVAC, refrigeration, gas, and fluid transfer systems, a flared tube can be connected to a male-threaded port using the precisely built Brass Flare Female Connector. This connector offers outstanding durability, corrosion resistance, and a long service life since it is made of premium forged brass alloys like CW617N or C37700.
Even in high-temperature and high-pressure settings, the flare connection ensures leak-free operation by forming a strong metal-to-metal seal. Without the need for extra sealing compounds, precision-machined threads enable dependable sealing and simple installation.
When reliable tube-to-port connections are needed, such as in air conditioning systems, refrigeration equipment, gas pipelines, hydraulic machinery, and industrial fluid control systems, brass flare female connectors are frequently utilized.
