Coated Braided Line 15in #3Hose -3Str/-3 90 Steel

The Coated Braided Line 15in #3Hose -3Str/-3 90 Steel by Allstar Performance is a precision brake hose assembly engineered for high-pressure fluid transfer in automotive and motorsport applications. This 15-inch braided hose serves as a critical hydraulic component in brake systems where reliable fluid delivery under extreme operating conditions is non-negotiable. Built for technicians and performance enthusiasts who demand durability and consistent performance, this hose bridges fuel system components with the precision fitting compatibility required in turbocharged, supercharged, or race-prepared engine bays.

This assembly features a stainless steel braided construction wrapped in black vinyl coating for abrasion resistance and environmental protection against fuel, oil, and corrosive vapors. The PTFE (polytetrafluoroethylene) inner lining ensures chemical compatibility and reduces friction during fluid flow, minimizing pressure loss over the 15-inch run. The #3 AN (Army Navy) hose standard provides a nominal 3/16-inch bore diameter—industry standard for mid-range brake and fuel applications. Termination includes a 3 AN straight female connector on one end and a 3 AN 90-degree female connector on the opposite end, allowing flexible routing around engine bay obstacles without kinking or crimping the line. This configuration is typical in custom brake line installations where space constraints or component positioning demand offset connection angles.

Technicians installing custom brake systems, performance upgrades, or engine swaps benefit most from this hose's standardized AN fittings and proven materials. The 15-inch length suits mid-engine builds, cross-mounted radiator configurations, or remote brake proportioning valve setups where factory line routes are incompatible. Compatibility extends to any brake system using #3 AN fittings—common in street rods, kit cars, circle-track vehicles, and modern race platforms. Proper installation requires torquing AN fittings to specification (typically 15–18 ft-lbs for #3 connections) to prevent leaks while avoiding over-tightening that can crack the fitting body. This hose should be secured against vibration using P-clips or adhesive-backed mounting hardware to prevent resonance failure during extended high-load braking events.
