Earl's Performance Aluminum AN Reducer Fittings

Earl's Performance Aluminum AN Reducer Fittings are precision-machined adapters engineered to provide seamless, leak-free transitions between different AN line sizes. Built on a heritage rooted in military aircraft-grade specifications, these reducer fittings deliver the consistent quality and reliability that have made Earl's a trusted name in professional motorsports plumbing since 1955.

Key Features:

• Hard anodized aluminum construction — Earl's ANO-TUFF™ hard coat anodizing process penetrates deep into the material, providing superior wear and corrosion resistance that outlasts conventionally anodized fittings
• Precision machined to exacting tolerances, ensuring consistent, leak-free connections across every fitting in the line
• Optimized internal flow path minimizes restriction and pressure drop during AN size transitions, maintaining system efficiency under demanding conditions
• Low-profile design reduces clearance issues in tight engine bays and custom fabrication environments
• Lightweight aluminum construction keeps overall system weight to a minimum without sacrificing strength or long-term durability
• Made in the USA — manufactured to the same rigorous standards trusted by professional racing teams across every major motorsport discipline
• Broad application range — suitable for fuel systems, oil systems, cooling systems, power steering, and virtually any custom plumbing configuration requiring an AN size transition
