9/16-20 Banjo Bolt Chrysler Master Cylinder

The 9/16-20 Banjo Bolt Chrysler Master Cylinder by FRAGOLA is a precision-engineered brake line adapter designed for custom and restoration brake system builds on Chrysler platforms. This banjo bolt serves as the critical connection point between your flexible brake hose and the master cylinder, translating brake fluid pressure from the pedal assembly directly to your hydraulic lines. Whether you're upgrading a classic muscle car, modernizing a vintage Chrysler, or fabricating a custom brake system from scratch, this banjo bolt ensures a leak-free, pressure-rated seal that won't compromise stopping power.

FRAGOLA's banjo bolt uses a dual-seal design with integral washers that clamp the hose end fitting securely against the master cylinder port, eliminating the need for separate crush washers and reducing assembly time. The 9/16-20 thread specification is the OEM standard for Chrysler master cylinders, ensuring proper fitment and pressure rating up to high-performance braking demands. Machined from corrosion-resistant material, the bolt withstands repeated thermal cycles, moisture exposure, and vibration without weeping or leaking—critical factors when brake fluid integrity directly affects safety. The compact design at 1.45 inches in length fits within stock or custom-fabricated brake line routing without interference.

Mechanics and fabricators rebuilding Chrysler, Dodge, or Plymouth brake systems will find this banjo bolt essential for both stock restoration and performance applications. Installation is straightforward: insert the hose fitting into the master cylinder port, thread the banjo bolt hand-tight, then torque to spec using a wrench to prevent cross-threading. This single component eliminates the frustration of incompatible adapters or hose fittings that don't seat properly, making it ideal for DIY restoration projects, professional shop work, and competition builds where reliability is non-negotiable.
