30in #4 Line -4 Str/-4 Str

The ALLSTAR PERFORMANCE 30-inch #4 Line -4 Straight/-4 Straight brake hose is a precision hydraulic component designed for high-performance automotive and motorsports applications where reliable fluid transfer under pressure is critical. This 30-inch brake hose assembly features 4 AN straight female connections on both ends, enabling seamless integration into custom brake systems without adapters or fittings that could introduce weak points.

Construction centers on braided stainless steel with PTFE lining—a combination that delivers corrosion resistance and thermal stability essential in demanding environments. The braided stainless outer sleeve protects against abrasion and impact during installation and operation, while the PTFE (polytetrafluoroethylene) inner lining resists fluid degradation and maintains consistent pressure delivery across temperature extremes. The 4 AN size (matching 1/4-inch nominal diameter) suits mid-range hydraulic systems found in drag racing, off-road recovery, and high-performance brake upgrades where flow capacity and response time matter equally.

Technicians and fabricators building custom brake lines benefit from ALLSTAR's direct female-to-female configuration, which eliminates the need for intermediate male adapters and reduces potential leak points. The 30-inch length accommodates routing flexibility in engine bays, frame rails, and suspension installations where standard pre-made hoses fall short. This hose is sold as a single unit, allowing builders to integrate it into larger brake system assemblies tailored to their specific vehicle geometry and performance requirements.
