42in #4 Line -4 Str/-4 Str 5pk

The 42in #4 Line -4 Str/-4 Str 5pk from ALLSTAR PERFORMANCE delivers professional-grade brake hose assemblies designed for high-performance automotive applications where reliability and precision matter. These braided stainless steel hoses with PTFE inner lining are built for custom fuel systems, brake lines, and power steering circuits in race cars, street rods, and modified vehicles. A 5-pack configuration ensures you have spares on hand for multiple system runs or future upgrades without repeated reordering.

Each 42-inch hose features 4 AN (5/16-inch) diameter sizing with straight female fittings on both ends, enabling direct connection between components without adapters or bends. The PTFE (Teflon) inner lining resists fluid degradation and prevents swelling, while the braided stainless steel outer sleeve protects against abrasion, UV exposure, and high-temperature environments common in engine bays and underbody routing. This combination delivers the durability and safety margins required for fuel delivery, brake pressure, and hydraulic systems operating at sustained high pressures without flex failure or leakage.

Fabricators, engine builders, and serious hobbyists benefit most from this 5-pack when constructing or refurbishing fuel systems on LS swaps, carburetor conversions, and full brake line replacements in vintage and modified vehicles. The 42-inch length accommodates standard spacing in most engine compartments, though experienced installers may cut or bundle hoses for shorter runs. Installation requires standard AN wrenches and careful routing away from heat sources and moving components; secure routing with P-clamps prevents vibration-induced wear and ensures long service life.
