12in #4 Line -4 Str/-4 Str

The 12in #4 Line -4 Str/-4 Str from ALLSTAR PERFORMANCE is a professional-grade braided stainless steel brake hose engineered for custom vehicle builds, performance brake system upgrades, and high-demand automotive applications. This 12-inch hose assembly connects dual 4 AN straight female fittings, making it ideal for routing custom brake lines in engine bays where factory configurations don't accommodate modern upgrades or tight engine compartment layouts. Whether you're fabricating a custom brake system for a competition vehicle, street rod, or late-model performance car, this PTFE-lined hose delivers the reliability and durability expected in serious automotive work.

The hose features a braided stainless steel exterior that resists abrasion, corrosion, and thermal degradation—critical for brake systems exposed to high underhood temperatures and vibration. Its PTFE (Teflon) inner lining provides superior chemical compatibility with DOT 3, DOT 4, and DOT 5.1 brake fluids while maintaining consistent flow and pressure characteristics under demanding braking cycles. The dual 4 AN straight female ends accept standard 4 AN male fittings, allowing seamless integration into custom-fabricated brake circuits without adapters. At 0.16 lbs and measuring just 12 inches in length, this hose fits tight engine compartments while maintaining the structural integrity and burst-pressure ratings required for brake system safety.

Mechanics, fabricators, and performance enthusiasts rely on this hose for custom brake installations, master cylinder relocations, and modular brake proportioning setups. Its compact 12-inch length makes it perfect for short runs between components in tight engine bays or between brake calipers and proportioning valves. When building a brake system from scratch or upgrading an existing circuit, ensure all fittings are tightened to specification and that the hose is routed away from moving engine components, sharp edges, and exhaust heat sources for longevity and safety.
