JB U1-6D 3/8" SAE x 1/2" MPT Adapter

The JB Industries U1-6D is a high-performance half union flare adapter designed for professional HVACR applications. Engineered for the rigors of field use, this adapter features a 3/8" SAE flare connection by a 1/2" MPT (Male Pipe Thread), facilitating a secure transition between refrigeration lines and threaded components. Forged from premium C360 and C370 brass in the USA, the U1-6D provides superior tensile strength and corrosion resistance compared to lower-quality import fittings. This HVAC brass adapter handles vacuum and working pressures up to 5,000 psi, depending on the tubing material and conditions, making it an essential component for liquid line and suction line assemblies. The dryseal pipe threads are precision-machined to minimize potential leak paths and provide ample clearance for tightening flare nuts. It is compatible with copper, brass, aluminum, steel, and plastic tubing when used with a proper 45? flare, ensuring versatility across multiple system designs including hydronic and AC systems.

• Precision Machined: Manufactured in the USA to AHRI and SAE J513 standards for a perfect, leak-free seat.
• High Pressure Rating: Capable of handling up to 5,000 psi in optimal conditions, suitable for high-pressure refrigerants.
• Durable Construction: Heavy-duty forged brass eliminates the risk of cracks and provides excellent vibration resistance in the field.
• Universal Compatibility: Works seamlessly with various tubing materials including soft copper and aluminum tube.

• What tube materials can I use with this adapter? It is designed for use with copper, brass, aluminum, steel, and plastic tubing, provided a compatible flare can be formed.
• Are the threads standard NPT? Yes, the 1/2" MPT side uses standard male pipe thread designed for a tapered, dryseal fit into NPT female ports.
• Does this require a flare gasket? No, when used with a standard 45? SAE flare, the metal-to-metal contact creates the seal without the need for additional gaskets or tape on the flare side.
