9in #4 Line -4 Str/-4 90 Deg 5pk

The 9in #4 Line -4 Str/-4 90 Deg 5pk from ALLSTAR PERFORMANCE is a professional-grade brake hose assembly set engineered for high-performance automotive hydraulic systems. This five-pack configuration delivers the flexibility and precision needed for custom brake line routing in competition vehicles, restorations, and modified street cars where factory-location fittings won't work. Mechanics and fabricators rely on these hose sets to create clean, efficient brake circuits without compromise on safety or reliability.

Each 9-inch hose features a 4 AN (5/16-inch) bore with PTFE (polytetrafluoroethylene) inner lining—the industry standard for DOT-compliant brake fluid compatibility and thermal resistance. The braided stainless-steel outer cover protects against abrasion and corrosion while maintaining flexibility for tight-radius bends during installation. The combination of a straight female 4 AN fitting on one end and a 90-degree female 4 AN fitting on the other allows single-handed, compact transitions in confined engine bays or frame rails, eliminating the need for separate adapters and reducing potential leak points in your braking circuit.

This hose set is ideal for builders executing custom brake line layouts in drag cars, road-course machines, and show vehicles where off-the-shelf hardline configurations fall short. The 5-piece package reduces inventory waste and provides spares for prototype fitting or future modifications. Verify compatibility with your 4 AN system components before installation; these hoses mate directly with standard inverted-flare and JIC fittings found on master cylinders, proportioning valves, and wheel-end brake calipers in modern performance applications.
