HVAC Brass Flare Connector with Copper Tube Tail – Refrigeration,45° SAE flare x solder. Forged brass body with copper tube tail. SAE J512/J513 compliant. Connects flare joints to brazed tubing without extra adapters. Sizes 1/4″ to 3/4″. 700 psi rated.
Our Brass Flare Connector with Copper Tube Extension is a precision-machined fitting designed to transition between a 45° SAE flare connection and a soldered copper tube in air conditioning, refrigeration, and heat pump systems. The brass body features a male flare end with a forged hex nut, while the copper tube tail provides a solder-ready connection point.
Manufactured from forged brass with a high-purity copper tube, it offers high mechanical strength, vibration resistance, and a pore-free structure that prevents refrigerant seepage. The 45° flare seat creates a metal-to-metal seal that can be assembled and disassembled repeatedly without brazing, making it ideal for service access and field repairs where soldering is impractical.

Flare x Solder Transition – Connects a flare joint directly to brazed copper tubing without additional adapters, simplifying installation and reducing potential leak points
Forged Brass Construction – Eliminates porosity and seepage risk found in cast fittings, ensuring a leak-proof seal under high pressure and vibration
Copper Tube Tail – High-purity copper tube provides a reliable solder joint with standard brazing practice
45° SAE Flare Seat – Precision-machined flare seat creates a reliable metal-to-metal seal that can be assembled and disassembled repeatedly without damage
Vibration Resistant – Forged structure withstands vibration in compressor lines better than machined or cast fittings
Wide Temperature Range – -53°C to +121°C, suitable for both cold-storage and high-heat HVAC applications
Connecting flare service valves to soldered refrigerant lines
