12in #3 Line -3 Str/-3 90 Deg 5pk

The 12in #3 Line -3 Str/-3 90 Deg 5pk from ALLSTAR PERFORMANCE is a purpose-built brake hose assembly designed for high-performance automotive applications where custom routing and precise fluid delivery are non-negotiable. This five-pack set addresses the real-world challenge every serious mechanic encounters: factory brake line layouts often don't accommodate aggressive suspension geometry, engine swaps, or relocated components. Whether you're building a track car, modifying a street performance vehicle, or fabricating a custom brake system, having pre-assembled hose segments in critical configurations eliminates guesswork and reduces assembly time without sacrificing safety or flow integrity.

Each 12-inch hose features a 3 AN (equivalent to -3 SAE) rating, meaning they're engineered to safely convey brake fluid under extreme pressure and thermal cycling without expansion or degradation. The straight female to 90-degree female configuration allows for directional flexibility at connection points—critical when space is tight or when you need to transition from vertical runs to horizontal layouts without additional fittings. All five hoses are constructed with braided stainless steel outer jacketing paired with PTFE (polytetrafluoroethylene) inner lining, a combination that resists abrasion, kinks, and brake fluid degradation while maintaining consistent performance across sustained braking loads. This design prevents the common failure mode where rubber-lined hoses degrade under DOT 3/4 fluid exposure or high-temperature track use.

Professionals building custom brake systems—from circle track competitors to street rod fabricators to suspension upgrade specialists—rely on pre-assembled hose packs to maintain consistency and reduce labor time on the lift. The five-piece configuration provides enough segments to handle both primary brake circuit runs and secondary applications like proportioning valve setups or clutch line replacements on manual transmission vehicles. Installation requires standard AN wrench sizes (typically 9/16" or 5/8") and basic line routing planning; these hoses integrate seamlessly with existing 3 AN male fittings, adapters, and manifolds already in your shop or vehicle build. For anyone serious about brake system integrity—whether upgrading a daily driver or going all-in on a race build—this hose assembly set eliminates the need for field fabrication while guaranteeing DOT-compliant pressure ratings.
