Coated Braided Line 21in #3 Hose -3 90 Deg/-3 Str

The ALLSTAR PERFORMANCE Coated Braided Line 21in #3 Hose with -3 90 Deg/-3 Str fittings is a precision brake line assembly engineered for high-performance and custom automotive applications where reliability under demanding conditions is non-negotiable. Built for mechanics and enthusiasts who demand OEM-equivalent or superior performance, this 21-inch hose bridges critical brake system components with the durability and flow characteristics required for both street and track environments. Whether upgrading a classic car restoration, custom hot rod, or late-model performance vehicle, this braided assembly eliminates flex points that compromise brake feel and response.

Constructed from stainless steel braiding with black vinyl coating and a PTFE (polytetrafluoroethylene) inner lining, this hose resists abrasion, vibration damage, and corrosion while maintaining superior pressure retention and thermal stability. The -3 AN (3/16-inch) diameter sizing matches OEM and aftermarket caliper/proportioning valve ports on most compact systems, while the dual fitting configuration—one -3 AN 90-degree female and one -3 AN straight female—provides flexible routing around engine bays and suspension components. PTFE lining eliminates DOT fluid incompatibility issues and reduces swelling, ensuring consistent brake modulation across temperature extremes common in performance driving.

Mechanics installing custom brake systems, proportioning valve assemblies, or modular calipers on vintage restorations and street rods will find this 21-inch length ideal for bridging master cylinders to remote proportioning blocks or junction blocks without excess slack. The braided construction provides visual appeal under the hood while the 90-degree and straight female endpoints accept standard -3 AN male fittings, allowing quick integration into existing systems. Installation requires basic brake line wrench skills and careful bench-testing to confirm no kinking occurs at the 90-degree elbow during routing; the vinyl coating protects against chafing during final dress-up.
