Brass Flare Tee Union
Brass Flare Tee Union
039-DFTU
The Brass Flare Tee Union is a precision-engineered fitting designed to connect three flare tubes in a T-shaped configuration, allowing efficient branching or distribution of fluid and gas within piping systems. Manufactured from premium forged brass alloys such as CW617N or C37700, this fitting provides excellent mechanical strength, corrosion resistance, and long service life.
The fitting features 45° flare connections on all three ends, creating a secure metal-to-metal seal that prevents leaks and ensures reliable system performance. Its robust construction and precise machining make it suitable for high-pressure and temperature-variable environments.
Brass Flare Tee Unions are widely used in HVAC systems, refrigeration units, fuel distribution lines, hydraulic and pneumatic systems, and industrial fluid transfer applications, where dependable three-way connections are essential.
Key Features
Superior Material Composition: Made from lead-free, forged brass alloy CW617N/C37700, ensuring excellent resistance to corrosion, dezincification, and wear even in harsh environments such as marine, chemical, or outdoor applications.
Precision Machining: CNC-machined surfaces guarantee tight dimensional tolerances, flawless flare angles, and perfect thread engagement for superior sealing performance.
Flare Connection Design: Each port features a 45° flare angle conforming to SAE J512 standards, providing a reliable metal-to-metal seal that eliminates the need for thread sealants or PTFE tapes.
Thread Versatility: Available in SAE flare threads as standard with optional NPT, BSP, BSPT, and metric threads to suit international and custom requirements, supporting diverse piping systems worldwide.
High Pressure and Temperature Tolerance: Rated for pressures up to 800 PSI and temperature ranges from -65°F (-53°C) to 250°F (121°C), suitable for HVAC refrigerants, natural gas, fuel, and hydraulic fluids.
Surface Finishes: Default natural brass finish with options for nickel plating (for enhanced corrosion resistance) or chrome plating (for aesthetic appeal and additional surface protection).
Easy Installation & Maintenance: Designed for quick hand or wrench-tightening, this tee union is serviceable and reusable, allowing for easy disassembly and reassembly during system maintenance or upgrades.
