72in #4 Line -4 Str/-4 Str

The 72in #4 Line -4 Str/-4 Str is a precision AN hose assembly engineered for high-performance hydraulic and fuel system applications where reliable fluid transfer is non-negotiable. Built by ALLSTAR PERFORMANCE, this 72-inch hose serves racing engines, performance vehicles, and demanding industrial systems requiring consistent pressure containment and leak-free connections. The straight-to-straight female fitting configuration ensures compatibility with standard AN components, making this assembly essential for builders and technicians who demand automotive-grade durability.

This hose assembly features braided stainless steel construction combined with a PTFE (Teflon) inner lining, delivering superior chemical resistance and temperature stability across a wide operating range. The stainless braid prevents hose expansion under pressure while the PTFE core eliminates compatibility issues with modern fuels and solvents. The 4 AN size (which translates to 1/4-inch nominal flow diameter) handles moderate to high flow rates typical of fuel distribution, coolant circulation, and brake pressure systems. Each unit is assembled as a complete, ready-to-install solution—no field fittings required—reducing assembly time and human error on the bench or in the engine bay.

Drag racers, street rod enthusiasts, and OEM restoration specialists choose this 72-inch length for fuel line runs, coolant bypass circuits, and power steering applications where standard rubber hose cannot survive the heat or chemical exposure. The dual straight female terminations allow seamless connection to male AN fittings at both chassis and engine-mounted hardline endpoints. With a compact package weight of 0.443 lbs, installation is straightforward without adding significant mass to the vehicle frame. This assembly is sold as a single unit and is engineered to withstand repeated thermal cycling and vibration inherent to motorsports and high-output engines.
