Product Details

Earl's Performance Ultra-Flex 45-Degree Crimp-On AN Hose End Fittings are purpose-engineered for use with Earl's Ultra-Flex PTFE hose lineup, delivering a precision-matched plumbing solution built for high-performance racing and professional motorsports applications. Exclusively compatible with Earl's Ultra-Flex 650 Kevlar-braided and 660 stainless-braided PTFE hose, these crimp-on fittings ensure a fully optimized, high-integrity assembly from end to end.

The 45-degree angle configuration is designed to navigate tight engine bays and complex plumbing runs where straight fittings are impractical. The crimp-on design permanently locks the fitting to the hose, eliminating loosening under vibration or pressure — a critical advantage in competition environments. Installation requires Earl's Ultra-Flex hydraulic crimping machine, and aluminum crimp collars are sold separately.

Key Features:

  • Ultra-Flex Exclusive Compatibility: Engineered specifically for Earl's Ultra-Flex 650 Kevlar-braided and 660 stainless-braided PTFE hose for a precision-matched, performance-optimized assembly
  • Lightest Crimp-On Plumbing Solution: The crimp-on design delivers the lightest available plumbing option for race engine fluid systems, contributing to meaningful weight savings in competition builds
  • Full-Length Smooth Bore Flow Path: The smooth bore advantage of Ultra-Flex PTFE hose extends continuously through the entire fitting assembly, minimizing flow restriction and pressure drop
  • Mil-Spec Type III Hard Anodized Finish: PTFE-impregnated Mil-Spec Type III hard anodizing provides superior corrosion resistance, long-term durability, and enhanced internal flow characteristics
  • 45-Degree Routing Flexibility: Ideal for tight-clearance applications and complex hose routing in race and high-performance builds where straight fittings cannot be used
  • Broad AN Size Availability: Available across multiple AN sizes to suit fuel, oil, coolant, water, methanol, and other high-performance fluid system applications
  • Crimp Collar Sold Separately: Aluminum crimp collar is available separately; installation requires Earl's Ultra-Flex hydraulic crimping machine

About Earl's Performance Plumbing: Earl's Performance has supplied the racing industry with aviation-grade fluid transfer technology for over five decades. Founded in 1955 with a mission to bring military aircraft plumbing technology to motorsports, Earl's pioneered the racing aftermarket plumbing industry and continues to set the standard for engineering precision, material quality, and system-level performance that professional race teams and serious builders demand.
