Single Male Banjo Adaptr Bolt M12x1.25 to -8AN

The Single Male Banjo Adapter Bolt M12x1.25 to -8AN from VIBRANT PERFORMANCE is a precision fluid connection component designed for custom fuel system builds, brake line conversions, and high-flow cooling circuits where metric threaded ports must interface with AN (Army-Navy) standard fittings. This adapter fills a critical gap in modern vehicle modification, enabling builders to work with factory metric fuel rails, OEM brake components, and aftermarket manifold ports while maintaining the industry-standard -8AN connection format used across performance and racing applications.

Constructed with a male banjo bolt design, this adapter features an M12×1.25 metric thread on one end and a -8AN (½-inch) port on the other, allowing direct coupling to -8AN hose fittings, fuel pressure regulators, and block adapters without requiring stepped or multiple-stage conversions. The banjo bolt configuration distributes pressure load across a wider bearing surface, reducing stress concentration at the connection point and improving sealing integrity under high-pressure fuel delivery or brake system applications. VIBRANT PERFORMANCE's engineering ensures tight tolerances and corrosion-resistant plating to handle both gasoline and E85 fuel, as well as brake fluid compatibility for mixed-system conversions.

This adapter is essential for builders executing metric-to-AN conversions on turbocharged engines, fuel system retrofits, and custom cooling setups where factory M12×1.25 ports exist on fuel rails, thermostats, or intake manifolds. Street tuners, race engine builders, and enthusiasts upgrading to aftermarket fuel systems will find this fitting indispensable for eliminating awkward adapter stacks and ensuring leak-free connections. Installation requires only hand tools and basic AN hose assembly knowledge; pair it with quality -8AN braided hose and compatible banjo bolt sealing washers for professional results on your high-performance build.
