Brass Air Conditioner Forged SAE Fittings — a versatile connector engineered for reliability in flare and welding-base configurations. Crafted from solid brass, this adapter handles HVAC, refrigeration, and piping tasks with precision, delivering secure seals and durable performance across a range of environments.

Key features

• Material: Brass — forged construction for consistent strength and long-term corrosion resistance.
• Max Pressure: 229 PSI (1.6 MPa).
• Operating Temperature: -20 to 120 °C.
• Applications: air conditioning branch pipes, refrigeration equipment, ship pipes, copper water pipes, medical oxygen pipes, and similar systems.
• Thread compatibility: SAE sizes with corresponding UNF nut threads to accommodate common fittings.

Size options and thread compatibility

• 6.35 mm = SAE 1/4" (Fit Nut Thread 7/16"-20 UNF)
• 9.52 mm = SAE 3/8" (Fit Nut Thread 5/8"-18 UNF)
• 12.7 mm = SAE 1/2" (Fit Nut Thread 3/4"-16 UNF)
• 15.88 mm = SAE 5/8" (Fit Nut Thread 7/8"-14 UNF)
• 19.05 mm = SAE 3/4" (Fit Nut Thread 17/16" UNF)

Why choose this brass adapter

This forged brass adapter combines a welding flange base with a valve seat flare connection, delivering a secure seal under pressure while maintaining compatibility with widely used SAE UNF nut threads. Its broad temperature and pressure ratings make it suitable for challenging environments—from HVAC branch lines to maritime piping and medical oxygen applications listed in its scope.

Installation tips

• Prepare clean flare and seating surfaces to ensure optimal sealing.
• Choose the correct size to match the corresponding UNF nut thread to prevent cross-threading.
• Apply appropriate torque to achieve a reliable seal without over-tightening.
