JB T3-6D 3/8 x 1/2 x 3/8 Brass Tee

As a seasoned technician, you know that the integrity of a refrigerant circuit depends on the quality of your brass. The JB T3-6D Brass Tee is a professional-grade fitting engineered for heavy-duty ACR applications. This 3/8 SAE x 1/2 MPT x 3/8 SAE branch tee is machined from high-tensile C360 brass in the USA, providing superior corrosion resistance and structural strength compared to standard imports. The forged brass construction effectively eliminates the risk of stress cracking under high-pressure cycles, while the long dryseal pipe threads ensure a deep, leak-proof engagement even in high-vibration environments.

Designed for seamless integration into HVACR systems, the JB Industries T3-6D supports a wide range of media including refrigerant, oil, and air. With a primary pressure rating capable of handling up to 5,000 psi (depending on tube material), this flare x male pipe x flare tee is a reliable choice for field repairs and custom manifold builds. It meets SAE J513 standards, ensuring precise dimensions for 45-degree flare connections. When you are looking for a brass flare branch tee that stands up to the rigors of commercial refrigeration, this American-made component is the industry standard for durability and performance.

• Durable Forged Brass: High copper content (65%) offers maximum tensile strength and prevents porosity leaks.
• Precision Machined SAE 45? Flares: Ensures a tight, metal-to-metal seal with standard copper tubing.
• Corrosion Resistance: High-grade brass alloys withstand harsh environmental conditions and common refrigerants.
• Vibration Resistant: Engineered for stability in cooling systems and hydraulic service.
• American Made Quality: Manufactured by JB Industries in Aurora, Illinois, adhering to strict AHRI guidelines.

What is the maximum working pressure for this tee?
The fitting itself can handle up to 5,000 psi, though the system limit is often determined by the tubing or valve cores used (typically 800 psi for valve cores).

Is this fitting compatible with R410A systems?
Yes, the robust brass construction is suitable for high-pressure refrigerants like R410A when used with compatible ACR tubing.

Do I need a thread sealant for the MPT connection?
Yes, for the 1/2" MPT center branch, a professional-grade thread sealant is recommended to ensure a gas-tight seal.
