Coated Line #4Str to Str Steel Ends 48in

The ALLSTAR PERFORMANCE Coated Line #4 Straight to Straight Steel Ends 48-inch brake hose is a professional-grade hydraulic assembly built for high-pressure fluid delivery in performance and racing applications. This 48-inch coated brake hose features 4 AN (AN4) straight female fittings on both ends, making it a direct replacement or custom fit option for brake systems, fuel systems, and power steering circuits where SAE J518 AN standard fittings are specified.

The hose construction combines a PTFE (polytetrafluoroethylene) inner line with braided stainless steel reinforcement and a black vinyl outer coating. PTFE lining resists chemical degradation and maintains flexibility across temperature ranges common in motorsports and hydraulic systems, while the stainless steel braid provides burst strength and resistance to abrasion. The black vinyl jacket protects against UV exposure, ozone, and moisture, extending service life in demanding environments. At 0.39 lbs and a compact 48-inch length, this assembly integrates into tight engine bays and component mounting areas without excess slack.

Technicians and fabricators select AN hose assemblies of this specification for custom brake line routing, fuel system upgrades, and power steering modifications in race cars, hot rods, and off-road vehicles where reliability under pressure is non-negotiable. The straight-to-straight female configuration allows direct connection to male AN4 ports, banjo fittings, or adapter blocks without additional reducers. ALLSTAR PERFORMANCE products meet industry standards for pressure cycling and burst testing, making this hose suitable for both street and competition use where fluid integrity and system consistency matter.
