JB T3-10D 5/8 x 1/2 x 5/8 Brass Tee

The JB Industries T3-10D is a high-performance 5/8 x 1/2 x 5/8 Brass Tee engineered for the rigorous demands of professional HVACR systems. Specifically designed as a 5/8 SAE Flare x 1/2 MPT x 5/8 SAE Flare fitting, this component is forged from premium C360 and C370 brass, ensuring high tensile strength and superior resistance to corrosion. Unlike lower-quality imported alternatives, the JB T3-10D is machined in the USA to meet strict SAE J513 and AHRI standards, providing a reliable, leak-proof seal in both vacuum and high-pressure environments up to 5,000 PSI depending on system conditions. This heavy-duty brass refrigeration fitting is compatible with a wide range of materials, including copper, brass, and aluminum tubing. Its thermal stability makes it suitable for temperature ranges from -20°F up to +220°F, supporting advanced R410A refrigerant applications and standard oil-based systems without degrading the integrity of the connection.

• Engineered Integrity: Forged brass construction minimizes the risk of cracking and fatigue in high-vibration commercial HVAC environments.
• Precision Threading: Long dryseal pipe threads provide more clearance for tightening flare nuts and help minimize potential leak paths.
• Broad Compatibility: Optimized for use with most modern refrigerants, including A2L-ready systems, alkylates, and diluted mineral acids.
• Field-Proven Reliability: Manufactured in the USA to exceed ASME and SAE standards, ensuring consistent performance for professional contractors.

What is the maximum pressure rating for the JB T3-10D?
This fitting is designed to handle pressures up to 5,000 PSI, though the specific working pressure often depends on the tubing material and flaring technique used by the technician.

Can I use this tee with R410A systems?
Yes, the high-copper-content brass and precise machining meet the requirements for R410A and other high-pressure refrigerants typically found in residential and commercial service.

Are these fittings compatible with aluminum tubing?
The JB T3-10D is compatible with aluminum, copper, steel, and plastic tubing, provided a proper flare is generated to ensure a metal-to-metal seal.
