The ALLSTAR PERFORMANCE 18in #3 Line -4 Str/-4 Str brake hose is a precision hydraulic assembly engineered for high-pressure fluid transfer in performance braking systems. Manufactured from braided stainless steel with PTFE internal lining, this 18-inch hose accommodates 3 AN line sizing with dual 4 AN straight female fittings, delivering reliable fluid delivery in racing, off-road, and heavy-duty automotive applications where brake line integrity is critical.
The stainless steel braided construction provides superior abrasion resistance and corrosion protection compared to rubber-only hose, essential in harsh environments where moisture, salt, and debris exposure accelerates degradation. PTFE inner lining maintains consistent flow characteristics under sustained thermal cycling and prevents fluid degradation, while the dual 4 AN straight female configuration ensures compatible fitment with standard AN adapter ecosystems. At 18 inches in length, this hose bridges moderate distances in engine bay or frame-mounted hydraulic layouts without excess slack or tension stress on fittings.
This assembly serves performance enthusiasts, racing teams, and off-road operators who demand dependable brake system architecture. Relevant for custom brake line installations, hydraulic system rebuilds, and situations requiring replacement hose that meets DOT and racing organization fluid pressure standards. The braided stainless design tolerates temperature swings from cold ambient starts to sustained high-speed braking heat, maintaining structural integrity where standard hose fails.
ALLSTAR PERFORMANCE manufactures hoses for both street and competition use, and this -4 Str/-4 Str configuration is a common specification in modular brake system designs. The lightweight footprint (0.16 lbs) minimizes unsprung mass while the compact dimensions (5.95 x 0.6 x 8.75 in) simplify packaging in tight engine compartments. Purchase as a single unit for targeted replacement or stock multiples for complete system overhauls.
