21in #3 Line -3 Str/-3 Str

The ALLSTAR PERFORMANCE 21in #3 Line -3 Str/-3 Str brake hose is engineered for custom and high-performance vehicle builds where precision hydraulic line routing is non-negotiable. This 21-inch braided stainless steel hose serves mechanics and enthusiasts who demand OEM-quality brake systems with the flexibility of aftermarket customization. Whether you're fabricating a fuel system bypass, installing a custom brake proportioning valve, or routing brake lines through a modified engine bay, this hose delivers the reliability that separates a weekend project from a competition-grade installation.

Built with a PTFE (polytetrafluoroethylene) inner liner, this brake hose resists thermal degradation and maintains consistent pressure integrity under the extreme conditions of track days, drag racing, or daily-driven performance vehicles. The braided stainless exterior provides superior abrasion resistance compared to rubber-only lines, critical when lines pass near exhaust manifolds, sharp frame edges, or moving suspension components. Both ends feature 3 AN (AN3) straight female fittings, a universal industry standard that accepts JIC or AN male adapters, giving you maximum flexibility when integrating this hose into modular fuel, coolant, or brake system designs. At 0.14 lbs and measuring 21 inches in length, the hose balances lightweight construction with sufficient routing distance for mid-engine conversions, front-mounted fuel cells, or rear-mounted hydraulic reservoirs.

Fabricators and serious DIY mechanics rely on ALLSTAR PERFORMANCE hose assemblies because they eliminate variables during critical system builds. The straight-to-straight female connector configuration works seamlessly with PTFE or braided-line splitters, proportioning blocks, and modular valve manifolds commonly found in race-spec brake systems or fuel delivery networks. This hose excels in applications where OEM routing isn't an option—custom frame rails, composite chassis, or engine swaps where stock brake and fuel line paths no longer exist. Verify your fitting size (3 AN) matches your system's male adapter threads before ordering; this hose will not work with larger 4 AN or 6 AN systems. Install with quality hose clamps and protect against abrasion using split loom or adhesive-backed wrap in areas of high movement or heat.
