6in #3 Line -3 Str/-3 Str

The 6in #3 Line -3 Str/-3 Str braided stainless steel brake hose is purpose-built for custom hydraulic brake system installations where precision routing and compact runs are essential. Fabricated from full stainless steel braid with PTFE (polytetrafluoroethylene) lining, this 6-inch hose assembly connects dual -3 AN straight female fittings—a configuration favored by fabricators and performance mechanics upgrading OEM brake lines to remote-mounted master cylinders, proportioning valves, or aftermarket brake bias systems. At just 0.09 lbs and measuring 5.9 x 0.8 x 6.05 inches, it fits tight engine bays and custom firewall installations without excess weight or bulk.

PTFE lining resists fluid degradation, high temperature cycling, and corrosive brake fluid chemistry—critical when running modern DOT 4 or DOT 5.1 fluids at elevated pressures. The braided stainless exterior provides abrasion resistance, kink suppression, and superior flex life compared to rubber-lined alternatives, especially in engine bay vibration environments or where lines route past exhaust components. The -3 AN (3/16-inch ID) specification is the industry standard for single-circuit brake applications and proportioning valve feeds, offering adequate flow capacity while maintaining structural integrity under sustained braking loads.

Street rod builders, race car fabricators, and restomod mechanics rely on pre-assembled hose segments like this to shorten lead times and ensure consistent fitting geometry during final system assembly. The straight female-to-female configuration pairs seamlessly with adapter blocks, proportioning valves, and modular master cylinder mounts where two hardline sections meet a flex segment. Verify fitting compatibility with your specific brake component threads before ordering; confirm hose length against your brake line routing diagram to avoid kinks or over-extension.
