Earl's Performance Ultra-Flex 45° Crimp-On Wiggins Quick-Disconnect Hose Ends

Earl's Performance Ultra-Flex Crimp-On Wiggins Quick-Disconnect Hose Ends are engineered for competitive racing and high-performance applications where rapid fluid line changes, reliability, and weight savings are critical. Designed exclusively for use with Earl's Ultra-Flex 650™ hose, this professional-grade hose end line replaces traditional threaded connections with a threadless quick-disconnect system — dramatically reducing installation time and enabling fast line changes in the most demanding racing environments.

Key Features:

• Wiggins-style quick-disconnect design — threadless male and female configurations allow fast, tool-free connections and disconnections across a range of AN hose sizes
• Compatible with Adel Wiggins clamshell closures (sold separately) for secure, consistent coupling in high-vibration environments
• Mil-Spec Type III Class 1 hard anodized finish for superior corrosion resistance and long service life
• PTFE-impregnated internals extend the smooth-bore flow advantages of the Ultra-Flex 650™ hose through the entire assembly, reducing friction and improving fluid flow efficiency
• Plasma-coated nitrile o-rings on male ends deliver exceptional seal longevity and leak-free performance
• 45-degree angled configuration optimizes hose routing in tight or congested engine bays and chassis plumbing runs
• Crimp-on installation creates a permanent, leak-free connection capable of withstanding high pressure and vibration
• Lightweight aircraft-grade aluminum construction minimizes plumbing system weight without sacrificing strength or durability

This product line is available in both male and female Wiggins quick-disconnect configurations across multiple AN hose sizes, making it suitable for a wide range of racing plumbing applications including fuel delivery, oil systems, and coolant lines. Note: The aluminum crimp collar is not included and must be ordered separately.

Since 1955, Earl's Performance has brought aviation-grade fluid transfer technology to motorsport. The Ultra-Flex Wiggins Quick-Disconnect line continues that legacy — offering racing teams and performance builders a trusted, lightweight, and rapidly serviceable plumbing solution where absolute reliability is non-negotiable.
