Earl's Performance Straight Aluminum AN Swivel Coupling

Earl's Performance Straight Aluminum AN Swivel Couplings are precision-machined fittings engineered for high-performance racing, street performance, and custom plumbing applications. Built to Earl's exacting quality standards and manufactured in the USA, these couplings deliver reliable, leak-free fluid connections across fuel, oil, hydraulic brake, and other performance fluid systems.

Key Features:

• Ano-Tuff Hard Anodizing — Earl's proprietary hard-coat anodizing process penetrates deep into the aluminum, creating a surface that delivers superior wear and corrosion resistance
• Extended Durability — The Ano-Tuff coating lasts twice as long as traditional anodized finishes for long-term performance in demanding environments
• 360-Degree Swivel Design — Allows easy hose routing and alignment after installation without twisting or stressing lines
• Excellent Flow Capacity — Low-profile, precision-machined design ensures maximum fluid flow for fuel, oil, and hydraulic applications
• Precision AN Threads — The AN adapter side seals on the flare (cone), not the threads, ensuring correct fit and leak-free performance
• Lightweight Aluminum Construction — Ideal for weight-conscious racing and performance builds
• Multiple Thread Configurations — Available in male-to-male, female-to-female, male-to-female, and swivel-to-swivel configurations in AN thread standards
• Made in the USA — Manufactured to Earl's strict quality standards
