Grade 5 Titanium Double Banjo Bolt
Key Features
● Stable Hydraulic Pressure Transfer Under Hard Braking
Grade 5 titanium has ≥825 MPa yield strength. This helps the titanium double banjo bolt resist elastic deformation during repeated heavy braking. Hydraulic pressure stays more consistent across high-load brake cycles.
● Brake Fluid Compatibility for Long Service Life
Titanium forms a stable passive surface and performs well around DOT 4 and DOT 5.1 brake fluids. The double banjo bolt helps keep threaded areas in better condition over time, making future brake line servicing easier.
● Pre-Drilled Safety Wire Hole for Race Preparation
The external hex head is machined with a locking wire hole before shipment. Workshops and race teams can install safety wire directly, reducing extra preparation work before race inspection.
● Lower Hardware Weight for Race and Custom Builds
Titanium is about 56% of steel density. The bolt keeps the strength required for hydraulic brake systems while reducing small hardware weight. In race and custom builds, those details often add up.
● Precision Fluid Passage and Sealing SurfacesEach double banjo bolt is machined from Grade 5 titanium. The internal fluid passage is smooth and precise. Accurate sealing surfaces help the crush washers seat properly for reliable hydraulic connections.
Installation & Maintenance Guidance
● Verify Thread Pitch and Engagement Depth Before Installation. M10×1.0 is common on many European motorcycles, while M10×1.25 appears more often on Japanese models. Maintain a minimum engagement depth of about 9–10 mm inside the caliper or master cylinder.
● Use Three Crush Washers for Dual Brake Line Installations. Use three crush washers when stacking two banjo fittings. Place one washer between the fittings and one on each outer side. Use hand tools or a torque wrench and follow 18–22 N·m as a reference range to avoid damaging aluminum threads..

Application Scenarios
Motorcycle Applications
● Front Brake Master Cylinder Dual Brake Line Connections
Mounted at the front brake master cylinder where separate hoses feed left and right calipers. The titanium double banjo bolt secures stacked banjo fittings in one outlet and keeps dual brake hose routing more compact.
● Front Brake Caliper Crossover Line Connections
Used where one caliper feeds a crossover brake line to the opposite side. One fastening point secures both banjo fittings and simplifies hose removal during brake service.
● Rear Brake Calipers in Linked or Dual-Circuit Brake SystemsOccasionally used where two hydraulic lines meet at rear brake assemblies. Seen in linked braking layouts and selected race builds with additional hydraulic circuits.
Extended Applications
● Dual-Circuit Hydraulic Handbrake Systems
Seen on drift cars and rally builds using independent hydraulic handbrakes. The titanium double banjo bolt secures stacked banjo fittings at the master cylinder and keeps hydraulic routing simpler around the assembly.
