42in #3 Line -4 Str/-4 90 Deg

The 42in #3 Line -4 Str/-4 90 Deg brake hose from Allstar Performance is engineered for high-pressure hydraulic systems in tactical vehicles, emergency response platforms, and heavy-duty automotive applications where reliability under extreme conditions is non-negotiable. This 42-inch braided stainless steel hose assembly connects hydraulic brake circuits with precision fittings, delivering the durability and performance demanded by law enforcement, military, and specialized transport operations. Built for systems requiring AN (Army-Navy) standard connectors, this hose is a critical component in maintaining brake integrity during demanding duty cycles.

The hose features a 3 AN line diameter with 4 AN straight female to 4 AN 90-degree female end connectors, allowing flexible routing through tight engine bays and around frame obstacles common in armored or modified platforms. Its braided stainless steel construction resists corrosion, abrasion, and vibration degradation—critical factors in vehicles operating in salt-spray, dust, or high-vibration environments. The PTFE (polytetrafluoroethylene) internal lining ensures chemical resistance and prevents fluid degradation while maintaining consistent pressure delivery. This combination of materials and design meets strict military and law enforcement specifications for brake system reliability and longevity.

This hose assembly is ideal for technicians maintaining or upgrading tactical vehicles, emergency response units, or high-performance platforms where stock hose routing or pressure ratings fall short. The 42-inch length accommodates most mid-size to full-size vehicle layouts, while the 90-degree elbow fitting on one end simplifies installation in confined spaces. Compatibility with standard AN brake systems and the lightweight 0.25 lb profile make this a direct replacement option for worn, damaged, or undersized original equipment. Proper installation requires torque specifications appropriate to AN fittings and system pressure ratings; consult manufacturer guidelines to ensure correct assembly and leak-free operation.
