21in #3 Line -3 Str/-3 90 Deg 5pk

The ALLSTAR PERFORMANCE 21in #3 Line -3 Str/-3 90 Deg 5pk is a professional-grade braided stainless steel brake hose set engineered for custom and high-performance automotive applications. As a mechanic working on modern suspension and braking systems, you'll recognize these hoses as essential components for upgrading factory rubber lines to a more reliable, custom-fit solution. This five-pack configuration gives you flexibility for multi-circuit brake system modifications, whether you're building a custom hot rod, installing a modern brake upgrade on a classic car, or fabricating a race-ready hydraulic braking setup.

Each hose measures 21 inches in length and features a 3 AN (AN3) diameter rating, with a straight female 3 AN connection on one end and a 90-degree female 3 AN fitting on the other—a versatile configuration that accommodates tight engine bay layouts and complex plumbing routes. The braided stainless steel construction resists abrasion, heat, and corrosion far better than OEM rubber hoses, while the PTFE (polytetrafluoroethylene) internal lining ensures compatibility with modern DOT 4 and DOT 5.1 brake fluids and provides consistent pressure delivery without expansion under thermal stress. The 90-degree termination allows you to run hose lines at right angles without bulky external adapters, reducing fitting count and potential leak points in your brake circuit.

This hose set is ideal for street rod builders, competition drag and road race mechanics, and anyone upgrading a vehicle's braking system with custom-fabricated steel lines. The five-piece quantity supports multi-circuit brake systems—front disc conversions, proportioning valve setups, or dual-master cylinder configurations—common in resto-mods and track-prepared vehicles. Installation requires basic line bending skills or access to a professional brake hose crimping service; the straight-to-90-degree pairing simplifies routing compared to all-straight or all-elbow alternatives. Compatible with any brake system using 3 AN fittings, these hoses are a cost-effective, durable upgrade for systems demanding precision hydraulic performance without compromise.
