Earl's Performance Ultra-Flex 650 Crimp-On AN Hose Ends

Earl's Performance Ultra-Flex 650 Crimp-On AN Hose Ends are purpose-built to complete a fully matched, high-efficiency fluid transfer system alongside Earl's Ultra-Flex 650™ Kevlar-braided hose. Engineered as part of a unified plumbing solution, these crimp-on fittings extend the performance advantages of the Ultra-Flex 650™ hose all the way through the fitting itself — delivering consistent, low-friction flow from end to end in racing and high-performance applications.

Key Features:

• Dedicated Ultra-Flex 650™ Compatibility: Engineered exclusively for use with Earl's Ultra-Flex 650™ Kevlar-braided hose, ensuring a fully integrated and optimized fluid transfer assembly
• Crimp-On Construction: Purpose-built crimp design delivers the lightest-weight plumbing option available for race engine and high-performance street builds
• Aircraft Aluminum Construction: Lightweight yet durable aluminum provides the structural integrity required for critical fuel, oil, coolant, and hydraulic plumbing systems
• Mil-Spec Type III Hard Anodized Finish: Military-specification anodizing delivers superior surface hardness and long-term corrosion resistance under extreme racing and performance conditions
• PTFE-Impregnated Anodizing: Teflon is impregnated directly into the fitting's anodized surface, significantly reducing internal fluid friction throughout the entire plumbing assembly
• Continuous Smooth Bore Flow Path: The low-friction, smooth bore flow characteristics of the Ultra-Flex 650™ hose carry seamlessly through the fitting — eliminating pressure drop at the connection point
• Multiple AN Sizes and Angles Available: The product line spans a range of AN sizes and bend angles to accommodate a variety of routing requirements across fuel, oil, coolant, and other fluid systems
• Crimper Tool Required: Requires a compatible crimp tool for installation; the aluminum crimp collar is available separately

What distinguishes these hose ends from conventional alternatives is Earl's advanced anodizing process, which impregnates PTFE directly into the aluminum fitting. This ensures the flow efficiency of the Ultra-Flex 650™ hose carries through the fitting without interruption — eliminating the typical performance bottleneck at the connection point. The result is a complete, high-efficiency plumbing assembly with consistent performance from hose to fitting.

Earl's Performance Plumbing has been a trusted name in motorsport fluid transfer for over five decades, bringing aviation-grade technology to high-performance automotive applications. These Ultra-Flex 650 Crimp-On Hose Ends uphold that legacy, providing race teams and performance builders with a professional-grade, ultralight plumbing solution built to perform under the most demanding conditions.
