28in #4 Line -4 Str/ -4 90 Deg 5pk

The 28in #4 Line -4 Str/ -4 90 Deg 5pk from Allstar Performance is a professional-grade brake hose assembly set designed for custom hydraulic brake systems in high-performance vehicles, race cars, and modified street machines. As a mechanic working on everything from vintage restorations to modern turbo builds, you'll recognize this as a core component for routing brake fluid with precision and reliability. This five-pack configuration provides flexibility for multi-circuit setups or gives you spares for future projects, eliminating downtime when brake lines need replacement or rerouting during engine bay modifications.

Each hose measures 28 inches in length and features -4 AN (5/16-inch) fittings with a straight female connector on one end and a 90-degree female connector on the other, offering the directional flexibility needed for tight engine compartments and complex brake layouts. The braided stainless steel construction resists abrasion, vibration damage, and corrosion—critical when hoses run near headers, exhaust systems, or high-heat zones common in performance builds. The PTFE (Teflon) inner lining ensures superior brake fluid compatibility, prevents internal degradation, and maintains consistent pressure delivery under extreme braking loads and extended track sessions. This combination of materials delivers the durability you need when pushing brake systems beyond factory limits.

Technicians and fabricators working on custom brake systems—whether converting to a dual-circuit setup, installing a proportioning valve, or rerouting lines for a chassis swap—will appreciate the mixed-fitting design and 28-inch length for adapting to non-standard configurations. The five-pack reduces per-unit cost while ensuring you have properly spec'd components for each circuit or junction point. These hoses comply with automotive hydraulic standards and work seamlessly with -4 AN fittings found on performance brake calipers, master cylinders, proportioning blocks, and distribution manifolds. Installation is straightforward: thread the fittings hand-tight, then finish with a wrench while supporting the fitting body to avoid twisting the hose.
