JB T3-6C Brass Tee

The JB T3-6C Brass Tee is a high-performance HVACR fitting engineered for vacuum pump intakes and refrigerant manifold configurations. Built from heavy-duty forged brass, this tee features 3/8" SAE flare connections on the run and a 3/8" MPT (Male Pipe Thread) center branch, ensuring a leak-proof seal in high-vacuum and high-pressure environments. Designed to meet SAE J513 refrigeration standards, the T3-6C provides the mechanical strength required for frequent make-and-break connections without thread galling. Its dryseal pipe threads offer superior clearance for tightening flare nuts, making it a reliable choice for field technicians working on A2L compatible systems or recovery equipment. This American-made brass fitting resists corrosion and maintains structural integrity under extreme temperature cycles, providing the durability needed for professional service tools and stationary refrigeration units.

Key Benefits

• Forged Brass Construction: High-tensile strength material reduces the risk of cracking under vibration or over-tightening.
• Standardized Compatibility: Fully conforms to AHRI and SAE specifications for universal fit with 3/8" refrigeration hoses.
• Vacuum Rated Performance: Precision-machined surfaces allow for deep vacuum pulls without atmospheric leakage.
• Corrosion Resistance: High copper content brass stands up to harsh refrigerants, alkylates, and mineral acids.
• Field Service Durability: Engineered for long-term use in HVAC/R recovery and evacuation setups.

Common Questions

Can this tee be used for R-410A systems?
Yes, the high-pressure brass forging is designed to handle the pressures associated with R-410A and other modern refrigerants, provided the corresponding flare nuts and tubing are correctly rated.

What is the maximum pressure rating for this fitting?
The JB T3-6C is typically rated for vacuum service and pressures up to 5,000 PSI depending on the specific application and connection type, though valve cores if present may limit working pressure.

Does this fitting require a sealant?
The 3/8" SAE flare connections rely on a metal-to-metal seal and do not require sealant. The 3/8" MPT branch should be installed with a compatible thread sealant or tape for a secure, leak-free joint.
