JB T3-6B 3/8 x 1/4 x 3/8 Brass Tee

The JB Industries T3-6B is a precision-engineered brass tee fitting designed for high-pressure HVACR service and reliable refrigerant management. Manufactured in the USA from heavy-duty, high-tensile C360 brass, this tee features 3/8 SAE Flare connections on the run and a 1/4 MPT (Male Pipe Thread) center branch. Engineered to meet strict SAE J513 and AHRI standards, the T3-6B maintains a vacuum rating down to 5,000 PSI depending on conditions, making it ideal for deep vacuum pulls and critical system charging. The forged brass body eliminates the risk of porosity and cracking common in lower-quality imports, while the long dryseal pipe threads provide extra clearance for flare nuts and ensure a leak-proof metal-to-metal seal. This ACR tube fitting is fully compatible with copper, aluminum, and steel tubing, providing the mechanical strength required for industrial refrigeration and hydraulic applications.

Key Benefits

• Maximum Durability: Forged from premium 2000 PSI-rated brass for superior resistance to vibration and thermal expansion.
• Engineered Precision: Strictly conforms to SAE J513 refrigeration standards for consistent thread engagement and sealing.
• Corrosion Resistance: High copper content (65%) protects against harsh environmental conditions and refrigerant oils.
• Universal Compatibility: Seamlessly integrates with 3/8 flare refrigeration lines and standard 1/4-inch NPT manifolds or ports.

Common Questions

What is the maximum pressure rating for the JB T3-6B?
While the fitting itself is designed to handle pressures up to 5,000 PSI, the maximum working pressure is often limited by the specific tubing or connected components used in the assembly.

Can this tee be used with R-410A systems?
Yes, the high-tensile forged brass construction is rated for high-pressure R-410A refrigerant applications and is compatible with standard alkylate and mineral oils.

Are these fittings made from lead-free brass?
These fittings are primarily designed for HVACR and hydraulic use; they are not intended for potable water applications and may contain trace elements of lead.
