JB T3-8C 1/2 x 3/8 x 1/2 Brass Tee

As a veteran tech, you know that the JB T3-8C Brass Tee is a staple for creating reliable manifold branches in high-pressure ACR environments. This American-made 1/2 SAE x 3/8 MPT x 1/2 SAE fitting is machined from premium C360 brass, providing the high-tensile strength and corrosion resistance required for long-term refrigeration service. Unlike lower-quality imports, these forged brass bodies are designed to eliminate the risk of cracking under thermal expansion or heavy vibration. With a vacuum rating of 5,000 psi depending on conditions, it is fully compatible with copper, aluminum, and steel tubing where a proper 45-degree flare can be generated. The long, dryseal taper pipe threads are specifically engineered to minimize potential leak paths and provide extra clearance for tightening your flare nuts in tight evaporator or condenser compartments. This tee strictly conforms to SAE J513 standards, ensuring seamless integration into your existing setup without the headache of non-standard dimensions.

• Forged Brass Construction: High copper content (65%) prevents fatigue and failure compared to cast alternatives.
• Extreme Pressure Capability: Rated for up to 5,000 psi vacuum and pressure, depending on system conditions.
• Precision Threading: Features 3/8 inch MPT dryseal threads for a secure, leak-free connection with minimal sealant.
• Trade Standard Compliance: Meets AHRI and SAE specifications for hydraulic, marine, and refrigeration applications.
• Broad Material Compatibility: Works with brass, copper, and aluminum tubing across all common refrigerants.

• What is the thread type for the middle port? The center run is a 3/8-inch Male Pipe Thread (MPT), while the two opposing ends are 1/2-inch SAE Male Flare.
• Can this be used for R-410A systems? Yes, the forged brass construction easily handles the high-pressure demands of R-410A and A2L refrigerants.
• Is this fitting suitable for vibration-heavy installs? While naturally resistant, we recommend using long flare nuts if the tee is installed near a compressor to maximize pull-out resistance.
