#4 Race-Rite Crimp-On Hose End Straight

The FRAGOLA #4 Race-Rite Crimp-On Hose End Straight is a precision aluminum hydraulic fitting designed for high-performance fuel, oil, and coolant system applications. This straight-inlet crimp hose end accommodates 4 AN hose size with a secure 4 AN female connection, making it the go-to choice for street rods, race vehicles, and custom engine builds where reliable fluid transfer and consistent fitting integrity are non-negotiable. The black anodized finish provides both corrosion resistance and a professional appearance in engine bays.

Constructed from lightweight aluminum, this FRAGOLA crimp fitting delivers the durability required for race-duty applications while keeping system weight minimal—critical for performance-focused vehicles. The crimp-on design eliminates the need for thread sealing and provides a permanent, vibration-resistant joint that won't loosen under high-pressure or high-temperature conditions typical of modified engines and turbo systems. The straight configuration suits applications where hose routing requires direct, uncompromised fluid flow without directional angles.

This fitting is engineered for builders and mechanics working with 4 AN plumbing systems—LS swaps, fuel system upgrades, custom cooling circuits, and dedicated oil lines. The Race-Rite product line from FRAGOLA is established in motorsports circles for repeatable quality and accurate sizing, ensuring compatibility with standard 4 AN hose and complementary fittings. A single unit covers one connection point; count your fittings carefully during system planning to ensure adequate inventory for complete circuits.
