The Russells RB-16-3-3 is a reducer fitting that adapts -16 AN connections to -3 AN sizes, enabling compatible fluid system integration across mismatched component specifications. Constructed from aluminum with an anodized finish, this fitting delivers corrosion resistance and durability in automotive and industrial fluid applications where size transitions are required.
Technical Specifications
• Product Type: Reducer Fitting
• Manufacturer: Russells (Russell Performance Products)
• Material: Aluminum alloy (6061-T6)
• Surface Treatment: Anodized finish
• Primary Size: -16 AN

– Key Features
Aluminum construction provides lightweight design without compromising structural integrity. The anodized surface treatment resists corrosion in harsh fluid environments and extends service life in demanding automotive and industrial settings. High-quality material processing ensures precision thread engagement and leak-free operation. The straightforward reducer geometry accommodates direct hose and fitting connections with minimal additional hardware.
– Typical Applications
This fitting addresses size transitions in automotive fuel systems, oil circulation circuits, and brake line assemblies. Industrial fluid delivery systems benefit from its ability to connect legacy and modern components with differing AN specifications. Installation in engine bay environments, fuel cell systems, and pressurized reservoirs is supported by the anodized aluminum construction.
– Compatibility & Integration
The -16 AN inlet accepts standard -16 AN male connectors; the -3 AN outlet threads to -3 AN female fittings and hose ends. Direct integration into existing AN-based plumbing eliminates the need for adapters or spacers in most configurations. The fitting maintains pressure integrity across size transitions in both low and high-pressure applications typical of automotive motorsports, fuel delivery, and hydraulic systems.
