12in #4 Line -4 Str/-4 90 Deg 5pk

The ALLSTAR PERFORMANCE 12-inch #4 Line -4 Straight/-4 90 Degree brake hose 5-pack (SKU ALL46402-12-5) is a high-pressure hydraulic line assembly engineered for motorsport and performance vehicles where brake system reliability is non-negotiable. Each hose in this set features a 12-inch length with 4 AN (¼-inch NPT) fittings in both straight female and 90-degree female configurations, allowing flexible brake line routing in compact engine bays and tight mounting scenarios common in race builds and heavily modified vehicles.

These hoses are constructed with braided stainless steel outer jacketing and PTFE (Teflon) lining—a critical combination for motorsport applications. The PTFE core provides chemical compatibility with DOT 3, DOT 4, and DOT 5.1 brake fluids while resisting swelling and degradation from high operating temperatures. The braided stainless exterior offers both abrasion resistance and corrosion protection in salt-air or high-vibration environments. The 4 AN (¼-inch) sizing handles the pressure demands of upgraded brake systems, ABS modules, and proportioning valves without flow restriction. The mixed-end configuration—pairing straight and 90-degree female fittings—eliminates the need for separate adapters or elbows, reducing connection points and potential leak sources in the brake circuit.

This five-pack is designed for builders constructing custom brake line harnesses, replacing damaged hose sections in race-prepped vehicles, or stocking backup assemblies for track support teams. The 12-inch length accommodates mid-engine layouts, rear-mounted master cylinders, and non-standard valve mounting without excess slack. Pre-assembled hoses eliminate field crimping, reducing assembly errors and ensuring consistent pressure ratings across the entire brake system. Each hose arrives ready to install with proper female-to-female coupling compatibility.
