90 Deg Alum #4 Flare 1/8 in Black

The 90 Deg Alum #4 Flare 1/8 in Black adapter by AEROQUIP is a precision hydraulic and pneumatic fitting designed to redirect fluid or air flow at a 90-degree angle while transitioning between two different port sizes and thread types. This adapter serves technicians, mechanics, and engineers working with industrial hydraulic systems, air brake lines, fuel systems, and pneumatic equipment where space constraints or system geometry demand an angled connection. The 90-degree configuration allows routing of hoses and lines around obstacles or into tight engine bays and compartments.

Constructed from aluminum and finished in black anodized coating, the 90 Deg Alum #4 Flare 1/8 in Black features a #4 AN (Army-Navy) male flare port on one end and a 1/8 inch NPT (National Pipe Thread) male port on the other, enabling compatibility across different system standards. The flare connection uses a 45-degree sealing cone that creates a metal-to-metal seal, ideal for high-pressure applications, while the NPT threaded port accommodates standard pipe-thread fittings common in industrial settings. Black anodizing provides corrosion resistance and a professional appearance while protecting the aluminum substrate in harsh environments.

This fitting is essential for custom hydraulic line assemblies, vintage automotive restorations, agricultural equipment, and industrial machinery where system reconfiguration or repair requires bridging between flare and NPT standards. Installation requires only a wrench or socket on both ports—no specialized tools needed. The compact 2.3 x 1.1 x 3.7 inch footprint and lightweight 0.04 lb design make it ideal for weight-sensitive or space-constrained applications. Verify that your system's pressure rating, fluid type, and temperature range align with AEROQUIP specifications before installation to ensure long-term reliability and safety.
