15in #4 Line -4 Str/-4 90 Deg Tube Style

The Allstar Performance 15-inch #4 Line -4 Straight to -4 90-degree tube style brake hose is a premium fluid transfer component built for high-pressure hydraulic systems in motorsports, off-road recovery, and performance vehicle applications. This 15-inch hose assembly features a stainless steel braided outer layer with PTFE (polytetrafluoroethylene) inner lining, delivering reliable performance in demanding under-hood and chassis environments where corrosion resistance and fluid compatibility are non-negotiable.

The -4 AN (Army Navy) rated connection standard provides a proven metric for high-pressure brake fluid transfer. This particular configuration combines a straight female -4 AN inlet with a 90-degree female -4 AN outlet, enabling flexible routing around engine bay obstacles and suspension components. The PTFE lining resists DOT-approved brake fluid formulations (DOT 3, 4, and 5.1) while the stainless steel braid adds abrasion resistance and structural integrity under vibration. At 0.19 lbs and compact dimensions (4.25 x 1.3 x 6.35 inches), the hose integrates cleanly into custom and OEM+ brake system layouts without adding significant weight or bulk.

This hose assembly targets builders and technicians upgrading brake systems on track cars, circle-track race vehicles, off-road trucks, and custom hot rods where factory hose routing or pressure rating proves inadequate. The 15-inch length accommodates mid-range run distances from master cylinder or ABS module to calipers or proportioning valves. Because brake system failure creates liability and safety risk, selecting AN-rated, braided, PTFE-lined hose from a recognized motorsports supplier like Allstar Performance ensures regulatory compliance and performance consistency across seasons and operating temperatures.
