Union AN 90 Degree Male -4

The Union AN 90 Degree Male -4 adapter from ALLSTAR PERFORMANCE is a precision-engineered fitting designed for high-performance hydraulic and pneumatic systems where space constraints demand a compact directional change. This 90-degree male-to-male AN coupling is essential for motorsports applications, race car fuel systems, and performance brake line assemblies where parallel or perpendicular routing is critical. Fabricated from aluminum with black anodized protection, this adapter provides reliable flow management in demanding environments.

The -4 AN designation indicates a nominal 1/4-inch hose bore, matched to standard -4 AN male ports on both ends to ensure leak-free connections with proper JIC flare fitting geometry. The 90-degree elbow configuration eliminates the need for hose bends in tight engine compartments or chassis areas, reducing stress on hose assemblies and minimizing vibration-induced failures. Black anodized aluminum construction delivers superior corrosion resistance while maintaining a lightweight profile—critical for race applications where every gram impacts performance. The compact dimensions (2.3 x 0.8 x 4.1 inches) and minimal weight (0.03 lbs) make integration straightforward in confined spaces.

This fitting serves racers, performance technicians, and custom fabricators who demand precision in fuel delivery, coolant recirculation, or brake circuits. The male-to-male configuration is ideal for connecting two hose assemblies or bridging components with existing -4 AN female ports. Installation requires standard -4 AN hose with appropriate JIC 37-degree flare ends; torque to manufacturer specifications to prevent leakage. Compatible with all fluid types—fuel, oil, coolant, and brake fluid—making it a universal solution for automotive, marine, and industrial hydraulic systems.
