4AN Non-Swivel Hose Ends Black 90

The REDHORSE PERFORMANCE 4AN Non-Swivel Hose Ends Black 90 is a precision-engineered fuel and fluid line fitting designed for custom automotive plumbing applications in high-performance engine builds, fuel injection systems, and hydraulic brake setups. This 90-degree hose end connects 4 AN hose directly to 4 AN female ports with a rigid, non-swivel design that eliminates flex and rotation—a critical requirement when routing fuel lines, coolant loops, or brake systems through tight engine bays where vibration and pressure cycling demand absolute reliability. Whether you're fabricating a custom fuel system for a street rod, turbo build, or dedicated race engine, this fitting provides the structural integrity and leak-proof seal necessary for sustained high-pressure operation.

Manufactured from aluminum and anodized in black for corrosion resistance and a clean, professional appearance, the 6090 series hose end features a 90-degree configuration that enables sharp bends without reducing line diameter or creating dead zones prone to vapor lock or sediment buildup. The non-swivel architecture means the fitting body remains stationary once installed—essential for applications where torque-down precision matters and any rotation could compromise hose alignment or system sealing. Weighing just 0.07 lbs and measuring compact dimensions (2.8 x 1.05 x 3.8 in), this fitting fits seamlessly into confined spaces typical of modern engine compartments while maintaining full flow capacity and pressure rating inherent to 4 AN sizing.

This hose end is ideal for fabricators, performance mechanics, and DIY builders installing custom fuel systems, intercooler loops, or transmission cooler lines where OEM routing won't work. The 4 AN sizing accommodates flow rates typical of high-output engines and turbo applications, while the rigid 90-degree design ensures consistent, repeatable installation across multiple identical builds. Pair this fitting with quality 4 AN hose, stainless braided lines, and proper thread sealant to achieve professional-grade fluid line systems that withstand decades of street driving or track duty without weeping or failure.
