Earl's Performance 180 Degree Aluminum AN Coupling

Earl's Performance 180 Degree Aluminum AN Couplings are precision-engineered fluid line connectors built for the rigorous demands of racing, motorsports, and high-performance street applications. Machined from high-grade aluminum, these couplings deliver an exceptional strength-to-weight ratio along with reliable, leak-free performance across a wide range of fluid system environments.

The 180-degree configuration creates a compact U-shaped flow path within a single fitting, allowing builders to reverse fluid flow direction without additional routing hardware or complex bends. This makes them an ideal solution for tight engine bays, chassis tunnels, and intricate plumbing layouts where straight or angled fittings simply cannot achieve the required routing geometry. A female-to-female swivel design simplifies installation and enables precise alignment without twisting or stressing the connected hose assembly.

Key Features:

• Precision-machined aluminum construction — purpose-built for performance and racing applications, delivering an excellent strength-to-weight ratio
• 180-degree U-turn flow path — reverses fluid flow direction within a single compact fitting, ideal for tight or complex plumbing runs
• AN (Army-Navy) standard threads — universally compatible with AN hose ends, adapters, and fittings across all major brands
• Female swivel design — enables easy, precise alignment during installation without stressing the hose assembly
• Multi-fluid compatible — suitable for fuel, oil, brake fluid, coolant, and other fluid system applications
• Anodized finish — provides corrosion resistance and a clean, professional appearance
• Available in multiple AN sizes — choose the correct variant to match your specific plumbing system requirements
