36in #4 Line -4 Str/ 1/8in NPT

The 36in #4 Line -4 Str/ 1/8in NPT brake hose from Allstar Performance is engineered for high-pressure hydraulic brake systems where reliability and precision matter. Whether you're building a performance vehicle, off-road rig, or competition platform, this braided stainless steel hose assembly delivers consistent performance in demanding environments. The 36-inch length accommodates flexible routing from master cylinder to remote caliper applications, giving builders and technicians the reach needed without compromise.

This hose features a #4 AN (5/16-inch) bore with a 4 AN straight female connector on one end and a 1/8-inch NPT straight male fitting on the opposite end, enabling direct integration with standard brake proportioning valves, master cylinders, and proportioning blocks. The PTFE (polytetrafluoroethylene) inner lining resists fluid degradation and provides smooth flow characteristics, while the braided stainless steel outer layer offers superior abrasion and corrosion resistance compared to rubber alternatives. This construction maintains structural integrity under pressure spikes and thermal cycling, critical in motorsports and high-performance applications where brake fluid temperatures regularly exceed 200°F.

Technicians, fabricators, and serious enthusiasts rely on Allstar Performance hoses for custom brake system layouts where OEM assemblies fall short. The mixed AN-to-NPT configuration bridges older and newer brake component standards, making this hose ideal for restoration projects, engine swaps, and custom fabrication builds. Proper installation requires stainless clamps rated for AN fittings and verification that brake fluid compatibility matches PTFE specifications—always refer to your brake system manufacturer's documentation and test pressure ratings before assembly.
