JB T3-4A 1/4 x 1/8 x 1/4 Brass Tee

The JB Industries T3-4A Brass Tee is a high-performance HVACR fitting specifically engineered for professional manifold service and refrigeration system maintenance. Constructed from premium-grade C360 brass, this 1/4" SAE x 1/8" MPT x 1/4" SAE tee offers superior tensile strength and corrosion resistance compared to lower-quality import alternatives. The forged brass body is designed to eliminate potential cracking and withstand vacuum pressures up to 5,000 psi depending on specific system conditions. Featuring dryseal taper pipe threads, the T3-4A minimizes the risk of leaks while providing the technician with ample clearance for tightening flare nuts. As a critical component in refrigeration gauge manifold setups, it ensures long-term reliability in high-vibration ACR environments. This heavy-duty brass flare fitting conforms to SAE J513 and AHRI standards, making it the industry standard for contractors who demand leak-free performance during evacuation and charging procedures.

• Engineered Precision: Manufactured from elite-level brass (65% copper, 35% zinc) to ensure maximum tensile strength and durability.
• High Pressure Rating: Capable of handling rigorous HVAC service demands with a working pressure threshold of up to 5,000 psi.
• Leak Prevention: Precision-machined SAE flare and MPT threads provide a reliable, airtight seal in critical vacuum and charging applications.
• Universal Compatibility: Fully compliant with SAE J513 and AHRI standards for use with standard HVAC manifold gauges.

What is the primary application for the JB T3-4A?
This tee is primarily used to adapt or expand refrigeration manifold ports, allowing technicians to connect 1/4" flare hoses to components or sensors with an 1/8" MPT connection point.

Is this fitting compatible with R-410A systems?
Yes, the forged brass construction and high pressure rating make it suitable for all high-pressure refrigerant charging and recovery operations, including R-410A and A2L systems.

Are the threads standard NPT?
The center port features an 1/8" MPT (Male Pipe Thread) which uses dryseal taper pipe standards for a secure fit, while the side ports are standard 1/4" SAE flare.
