#6 to 1/2-20 Inverted Flare Steel Fitting

The #6 to 1/2-20 Inverted Flare Steel Fitting is a precision hydraulic adapter designed to connect AN-style male ports to inverted flare male threads. This straight-configuration fitting serves critical roles in fluid power systems, fuel delivery lines, and brake applications where reliable, leak-free connections are essential. Whether you're working on motorsports equipment, aircraft hydraulics, or heavy machinery, this adapter bridges two common industrial thread standards with proven durability.

Manufactured by AEROQUIP, a trusted leader in fluid transfer solutions, this fitting is constructed from steel and finished with zinc oxide plating to resist corrosion and extend service life. The inverted flare design creates a face-seal connection that distributes load evenly across mating surfaces, minimizing stress concentration and reducing the risk of leakage under pressure. The #6 AN male port accommodates standard -6 hose or tubing, while the 1/2-20 inverted flare male thread accepts corresponding female adapters or component ports, making this fitting a versatile solution for system integration and modification.

Technicians, fabricators, and equipment manufacturers rely on this fitting when retrofitting hydraulic circuits, upgrading fuel systems, or assembling custom assemblies that require thread or port conversion. Its compact design—measuring 2.15 × 1.1 × 3.7 inches and weighing just 0.07 lbs—fits readily into tight engine bays and equipment enclosures without adding bulk. Proper installation requires compatible female 1/2-20 inverted flare ports and standard -6 AN hose fittings; apply appropriate thread sealant and torque to manufacturer specifications to ensure safe, code-compliant operation.
