30in #4 Line -4 Str/-4 90 Deg 5pk

The 30in #4 Line -4 Str/-4 90 Deg 5pk from Allstar Performance is a professional-grade brake hose assembly designed for high-pressure hydraulic systems in racing, motorsports, and heavy equipment applications. This five-pack bundle delivers OEM-quality components that meet stringent SAE specifications, making it an essential choice for technicians, fabricators, and field maintenance crews who demand reliability under demanding conditions. Whether you're rebuilding a brake system, fabricating custom hydraulic lines, or maintaining fleet equipment, these hoses provide the dependable performance required for safety-critical applications.

Each 30-inch hose features a 4 AN (1/4-inch) bore with braided stainless steel construction and PTFE (Teflon) internal lining—a combination that resists corrosion, maintains integrity under pressure cycling, and minimizes fluid contamination. The -4 Straight Female to -4 90-Degree Female configuration accommodates both inline and angled port connections, eliminating the need for additional adapters in complex routing scenarios. PTFE lining prevents swelling and degradation from mineral and synthetic brake fluids, while braided stainless reinforcement handles the pressure spikes and vibration loads inherent to motorsports and industrial hydraulics. The five-piece set reduces downtime by providing immediate replacements and extras for multi-circuit systems.

Technicians working on circle-track racing, drag racing, and road course platforms will find these hoses compatible with any SAE 4 AN port system, including manual and power brake conversions. The 30-inch length accommodates typical front-to-rear routing, engine-bay layout changes, and custom hydraulic circuits without requiring field modification. Installation is straightforward: ensure proper torque on compression fittings (typically 20–25 ft-lbs for AN connections) and route away from heat sources and sharp edges. Allstar Performance's reputation for motorsports-quality components ensures these hoses meet or exceed DOT and SAE standards for brake system integrity and safety.
