20in #4 Line -4 Str/-4 Str

The 20in #4 Line -4 Str/-4 Str brake hose from ALLSTAR PERFORMANCE is engineered for high-pressure hydraulic brake systems found in performance vehicles, race cars, and tactical equipment platforms. This 20-inch hose assembly connects directly between brake components using 4 AN (JIC) fittings on both ends, making it ideal for custom brake line routing where OEM hard lines prove inflexible or inaccessible. Built to withstand extreme pressure cycling and thermal stress, this hose is specified for professional-grade applications where brake system reliability is non-negotiable.

The 20in #4 Line features braided stainless steel construction wrapped around a PTFE (polytetrafluoroethylene) inner core, a combination that delivers superior pressure containment and chemical resistance. The inner PTFE lining resists degradation from modern brake fluid formulations and prevents internal corrosion that can compromise pressure integrity over time. The stainless steel braid provides abrasion protection and structural reinforcement, allowing the hose to maintain dimensional stability under the extreme pressure pulses inherent to high-performance braking systems. Both terminations are 4 AN straight female fittings, ensuring leak-free connections with standard JIC adapters and components.

Professionals in motorsports, custom fabrication, and vehicle performance upgrades rely on this hose for front-to-rear brake line runs or caliper-to-master cylinder applications where routing flexibility matters. The 20-inch length accommodates mid-range runs without excess slack that could create pressure lag. Installation requires basic brake system knowledge and proper line routing away from heat sources and moving components; secure the hose using industry-standard clamps at regular intervals to prevent vibration-induced wear. This hose is sold individually, so verify your complete brake system layout before ordering to ensure correct quantity and length for your application.
