9in #4 Line -4 Str/-4 90 Deg

The ALLSTAR PERFORMANCE 9-inch #4 Line -4 Straight/-4 90 Degree brake hose assembly is a precision-engineered hydraulic component designed for high-performance automotive applications. This 9 in brake hose features a 4 AN straight female inlet and a 4 AN 90-degree female outlet, enabling flexible routing in tight engine bay configurations where standard plumbing cannot accommodate direct connection.

The hose employs full braided stainless steel construction with PTFE (polytetrafluoroethylene) internal lining, a specification that matters because PTFE resists degradation from heat cycling and maintains structural integrity under sustained high-pressure brake system operation. Stainless braiding provides superior corrosion resistance in salt-air environments and consistent pressure retention across repeated hot-cold cycles—critical for street vehicles and competition platforms operating at thermal extremes. The 4 AN sizing handles flow requirements for modified or high-performance hydraulic systems without inducing excessive pressure drop or heat generation in the brake circuit.

This hose is built for builders and technicians who need reliable, compact brake line routing without fabrication. The 90-degree outlet fitting allows the hose to transition from one plane to another while the 9-inch length provides moderate run distance across engine bay segments. ALLSTAR PERFORMANCE is positioned in the premium end of performance brake component manufacturing, known for attention to fitting tolerances and materials validation. Applications range from street rod builds to track-oriented vehicles where every cooling advantage and clean plumbing layout matters.

Whether upgrading a dual-circuit brake system, routing around tight headers, or building a custom brake configuration, this hose eliminates improvised bends and leak-prone adapter chains. The specification sheet confirms a net weight of 0.15 lbs, appropriate for a composite assembly of this diameter and construction. Sold individually, allowing technicians and builders to source only the configurations needed for their specific platform.
