20in #4 Line -4 Str/-4 90 Deg Tube Style

The ALLSTAR PERFORMANCE 20in #4 Line -4 Str/-4 90 Deg Tube Style brake hose is engineered for high-performance brake systems where routing flexibility and reliable pressure containment are non-negotiable. Built for street rods, race cars, and heavily modified vehicles, this hose accommodates custom chassis layouts and engine bay configurations that demand unconventional brake line paths. Whether you're upgrading from factory steel hardlines to a braided system or fabricating a complete custom brake circuit, this 20-inch pre-assembled unit eliminates guesswork and delivers the consistent performance serious enthusiasts expect.

This brake hose features a 4 AN (AN4) straight female inlet and 4 AN 90-degree female outlet, allowing efficient transitions between hard brake lines and caliper-mounted or chassis-routed fittings. The PTFE (polytetrafluoroethylene) liner resists fluid degradation and heat soak better than rubber alone, critical when running modern synthetic dot-3, dot-4, or racing brake fluid in turbocharged or forced-induction applications. Braided stainless steel overbraid provides abrasion protection, vibration dampening, and visual appeal while maintaining burst-rated pressure integrity—the 20-inch length balances reach without unnecessary volume that could soften pedal feel or increase fluid expansion under thermal stress.

Mechanics and fabricators favor ALLSTAR hose assemblies for custom brake installs, retrofit projects, and motorsports builds where OEM hardlines won't fit modified suspension geometry or relocated brake masters. The combination of straight and 90-degree ports suits front-to-rear transfers, caliper remounting, and proportioning valve configurations common in street rods and competition vehicles. Installation is straightforward—ensure AN4 line ports match your caliper inlets and hard brake line outlets, use brass or stainless fittings rated for your brake fluid, and torque per hose manufacturer specs to prevent leaks. At 0.21 lbs, this single hose integrates seamlessly into complete custom brake systems without adding significant weight.
