Fitting Banjo Bolt Mal e 12mm x 1.0 Bolt 20mm

The Vibrant Performance Fitting Banjo Bolt Male 12mm x 1.0 Bolt 20mm Length is a precision hydraulic fitting component engineered for fuel system applications requiring robust, leak-free connections. Vibrant Performance's banjo bolts are industry-standard connectors used across performance vehicles, custom builds, and motorsport applications where fuel line integrity under pressure is non-negotiable.

This male banjo bolt features a 12mm x 1.0 metric thread with 20mm total length and includes integrated washers for reliable sealing. The black anodized aluminum construction provides corrosion resistance while maintaining lightweight characteristics—critical for engine bay applications exposed to fuel vapors, temperature cycling, and vibration. The anodized finish also protects against galvanic corrosion when paired with dissimilar metals in composite fuel systems.

Buyers integrating custom fuel rails, aftermarket fuel blocks, or rebuilding OEM fuel system components rely on banjo bolts to transition between rigid fuel lines and flexible hose connections. The metric 12mm thread pitch is standard across Japanese and European performance applications, making this fitting essential for carburetor conversions, fuel injection upgrades, and modified fuel systems on tuner vehicles and race builds. Proper torque and washer placement prevent weeping leaks that compromise fuel pressure and system reliability.

Vibrant Performance maintains tight tolerances on banjo bolt geometry to ensure consistent sealing surface contact, which is essential since fuel system pressure—typically 40–65 psi on carbureted engines and 45–65 psi on fuel-injected systems—will expose any gasket or thread anomalies. The included washers (crush washers in aluminum applications) must be replaced during reassembly to maintain integrity across multiple service cycles.
