6in #4 Line -4 Str/-4 Str

The 6in #4 Line -4 Str/-4 Str from ALLSTAR PERFORMANCE is a professional-grade braided stainless steel brake hose engineered for high-performance automotive applications where precision fluid routing and reliability are non-negotiable. Built for custom brake system installations, engine bay modifications, and competition vehicles, this hose assembly connects dual 4 AN straight female fittings in a compact 6-inch configuration. Whether you're rebuilding a race car brake circuit, upgrading to a custom-routed hardline system, or installing a remote brake bias adjuster, this hose serves as a critical junction point in systems where every connection must hold pressure and perform consistently.

Internally lined with PTFE (polytetrafluoroethylene), this 4 AN hose resists fluid degradation and maintains compatibility with DOT 3, DOT 4, and synthetic brake fluids while the braided stainless steel outer jacket provides abrasion resistance and visual durability in engine compartments exposed to heat cycles and vibration. The straight-to-straight female end configuration allows seamless integration into hardline or hose-to-hose transitions without adapter fittings, reducing connection points and potential leak pathways. At 0.13 lbs and measuring 6 inches in length, the compact footprint minimizes routing complexity in tight brake system layouts typical of tube-frame race cars, custom street rods, and heavily modified engine bays where space around the master cylinder and proportioning valve is severely limited.

This hose assembly is ideal for fabricators, race teams, and experienced brake system builders who demand OEM-equivalent pressure ratings and material integrity in custom installations. It pairs directly with 4 AN male hardline or hose fittings on both ends, making it essential inventory for anyone upgrading brake circuits on vehicles ranging from vintage hot rods to modern performance platforms. Installation requires basic brake system knowledge, proper flaring or hose end crimping, and careful pressure testing before operation to ensure system integrity under full braking loads.
