21in #3 Line -3 Str/-3 90 Deg Tube Style

The ALLSTAR PERFORMANCE 21-inch #3 Line -3 Straight/-3 90 Degree Tube Style brake hose is a precision hydraulic component engineered for high-pressure braking systems in racing and performance vehicles. Built from braided stainless steel with PTFE inner lining, this 21-inch hose assembly connects 3 AN straight female fittings on one end to a 3 AN 90-degree female fitting on the other, accommodating tight manifold layouts and complex brake line routing where standard configurations don't fit.

The stainless braided exterior provides corrosion resistance and abrasion protection in underhood environments, while the PTFE (polytetrafluoroethylene) internal bore resists fluid degradation and offers superior chemical compatibility with DOT 3, DOT 4, and synthetic brake fluids. The 3 AN port size handles the flow rates typical of modern high-performance brake systems without restriction. The 90-degree female end eliminates the need for separate adapters when space constraints require a right-angle connection, reducing potential leak points and simplifying installation in confined engine bays or frame rails.

This hose assembly is essential for custom brake line fabrication in road racing, autocross, track day vehicles, and high-performance street builds where OEM hose routing doesn't suit modified suspension geometry, relocated components, or aftermarket master cylinders and proportioning valves. The 21-inch length accommodates mid-length runs between brake calipers and remote proportioning blocks, balance bars, and master cylinder mountings. Each hose is individually tested and manufactured to ALLSTAR PERFORMANCE standards, a recognized supplier to racing teams and serious enthusiasts who demand reliability under sustained high-pressure operation.
