Adapter 45 #6 Flare 3/8in NPT

The Adapter 45 #6 Flare 3/8in NPT is a precision hydraulic and pneumatic fitting designed to bridge two industry-standard connection types in high-pressure fluid systems. This adapter serves technicians, equipment manufacturers, and maintenance professionals who need reliable transitions between AN (Army-Navy) flare fittings and NPT (National Pipe Thread) ports. Whether you're assembling custom fluid lines, repairing industrial equipment, or building aftermarket hydraulic systems, this adapter eliminates the need for multiple connection solutions.

Constructed from aluminum and finished in blue anodized coating, the Adapter 45 #6 Flare 3/8in NPT provides both durability and corrosion resistance in demanding environments. The 45-degree angle design optimizes flow characteristics and reduces turbulence in fluid lines, while the blue anodize protects the aluminum substrate from oxidation and wear. The male 6 AN flare connection accommodates standard AN fittings, and the male 3/8 inch NPT thread accepts conventional pipe threads, allowing seamless integration into existing systems without additional adapters or modifications.

This adapter works best for users installing custom hydraulic brake lines, fuel delivery systems, or pneumatic control circuits where space is limited and angle fittings improve clearance and routing efficiency. Its compact form factor—weighing just 0.04 lbs and measuring 2.85 x 0.8 x 4.6 inches—fits tight engine bays and equipment frames. Installation is straightforward: thread the NPT end into the female 3/8in NPT port using standard pipe-thread sealant, and connect the AN flare end to your 6 AN male fitting using the appropriate wrench size. Verify pressure ratings match your system specifications before use.
