48in #4 Line -4 Str/-4 90 Deg Tube Style 5pk

The 48in #4 Line -4 Str/-4 90 Deg Tube Style 5pk from Allstar Performance is a professional-grade brake hose assembly engineered for hydraulic and fluid line routing in high-performance vehicles, motorsports applications, and heavy-duty equipment. Professionals in law enforcement, military logistics, and tactical vehicle maintenance rely on quality hose assemblies to ensure reliable fluid transfer under demanding conditions. This five-pack configuration delivers multiple connection points for brake systems, fuel delivery, or coolant circulation, reducing the need for custom fabrication and installation time.

Each hose measures 48 inches in length and features 4 AN (Aeronautical Standard) sizing at both connection points—a straight female 4 AN end paired with a 90-degree female 4 AN end for directional flexibility around tight engine bays and frame constraints. The assembly utilizes braided stainless steel outer construction for abrasion resistance, vibration dampening, and durability in corrosive environments, while PTFE (polytetrafluoroethylene) internal lining prevents fluid degradation and ensures compatibility with synthetic brake fluid, gasoline, diesel, and coolant. This combination of materials withstands pressure cycles and thermal stress common in motorsports and tactical vehicle operations without premature cracking or leakage.

Vehicle builders, fleet maintenance personnel, and equipment technicians benefit most from this five-pack offering, as multiple assemblies enable complete brake or fuel system upgrades without ordering individually. The straight-to-90-degree configuration accommodates common brake distribution block layouts and fuel manifold geometries found in performance trucks, emergency vehicles, and specialized tactical platforms. Installation requires basic AN fitting tools and hose clamps compatible with 4 AN standards; ensure adequate routing clearance from heat sources and rotating components for optimal service life and safety compliance.
