9in #3 Line -3 Str/-3 Str

The 9in #3 Line -3 Str/-3 Str brake hose is a precision-engineered hydraulic line designed for custom and performance brake system builds where OEM configurations require replacement or modification. Built for enthusiasts and professional mechanics upgrading to braided stainless construction, this 9-inch hose delivers superior durability and reliability compared to rubber alternatives. Whether you're fabricating a custom brake layout, installing a upgraded master cylinder, or rebuilding a classic vehicle's hydraulic system, this hose bridges components with matched 3 AN fittings and consistent port sizing for leak-free operation.

Constructed with braided stainless steel outer sheathing and PTFE (polytetrafluoroethylene) inner lining, the 9in #3 Line offers resistance to abrasion, vibration, and thermal cycling that standard rubber hoses cannot match. The 3 AN straight female-to-female configuration allows seamless integration into hard-line and flexible brake systems, accommodating 45-degree or 90-degree adapters as your plumbing demands. PTFE lining prevents corrosion from brake fluid exposure and eliminates the swelling that can degrade rubber over time, ensuring consistent pedal feel and reliable pressure delivery to calipers or drum wheel cylinders across thousands of heat cycles.

This compact 9-inch length is ideal for bridging brake master cylinders to proportioning valves, connecting distribution blocks to remote reservoir systems, or linking dual-circuit master cylinders in street rod and race car applications. Its lightweight 0.1 lbs profile makes it suitable for weight-conscious builds without sacrificing strength. The hose works with any hydraulic brake system operating within standard automotive pressures and is compatible with DOT 3, DOT 4, and DOT 5 brake fluids, making it a universal upgrade for street performance, off-road, or vintage restoration projects requiring modern hydraulic reliability.
