Coated Line #4 Str to 90 Steel Ends 48in

The Coated Line #4 Str to 90 Steel Ends 48in brake hose from ALLSTAR PERFORMANCE is a premium hydraulic line engineered for precision brake system builds, custom fabrication, and high-performance engine bay layouts. Whether you're restoring a classic muscle car, constructing a race-ready bracket system, or upgrading an existing brake circuit, this 48-inch hose bridges critical hydraulic connections with proven reliability. The straight-to-90-degree configuration accommodates tight angles and space constraints without kinking, crush damage, or performance degradation—essential when routing lines through modern engine compartments or around performance modifications.

Built with braided stainless steel construction and PTFE (polytetrafluoroethylene) lining, this hose resists corrosion, thermal cycling, and chemical breakdown from brake fluid exposure. The black vinyl exterior coating adds abrasion resistance and protection against underhood heat and UV degradation, extending service life across seasons of hard driving or competition use. The 4 AN sizing (1/4-inch nominal bore) handles adequate flow rates for dual-circuit or proportioned brake systems without restrictive pressure loss, while both ends feature 4 AN female 90-degree connections, enabling seamless integration with aftermarket master cylinders, proportioning valves, calipers, and distribution blocks. PTFE lining prevents swelling and maintains consistent hydraulic response under sustained pressure and temperature fluctuations.

Mechanics and fabricators choose this hose for street rods, drag cars, drift builds, and vintage truck restorations where factory brake routing cannot accommodate modern brake component placement or when custom suspension geometry demands relocated cylinders. The 48-inch length provides flexibility for mid-engine layouts, rear-mounted master cylinders, or systems requiring extended runs from front-mounted proportioning blocks to rear caliper circuits. Installation requires standard AN fittings and wrenches; the straight and 90-degree female ends accept corresponding male-end brake lines, adapters, or quick-disconnect couplers. Always verify clearance to ensure the hose avoids sharp edges, exhaust components, and moving suspension members.
