Earl's Performance UltraPro 90-Degree Twist-On AN Hose End Fittings

Earl's Performance UltraPro 90-Degree Twist-On AN Hose End Fittings are purpose-engineered for motorsports and high-performance street builds, delivering race-proven fluid routing performance across fuel, oil, coolant, and brake system applications. Designed exclusively for use with Earl's UltraPro convoluted PTFE hose, these fittings are part of a fully integrated plumbing system where every component is optimized to work in concert for maximum strength, flow, and long-term reliability.

Key Features:

• Dynamic Swivel Technology — allows full 360-degree rotation of the assembled line after installation, eliminating hose stress and simplifying routing in complex engine bays and tight chassis environments
• Twist-On Design — tool-free attachment to Earl's UltraPro convoluted PTFE hose for fast, repeatable, and reliable connections at the shop or at the track
• 2024-T8 Aluminum Construction — high-stress components machined from aerospace-grade 2024-T8 aluminum, delivering superior strength over the 6061-T6 aluminum commonly used by competitors, with minimal weight penalty
• Furnace Dip-Brazed Bent Tube — mil-spec dip-brazing process creates a permanent, structurally superior bond engineered to withstand harsh environments, extreme pressures, and sustained vibration
• ANO-Tuff Hard Coat Anodizing — Earl's proprietary hard coat anodized finish provides extreme surface hardness and long-term corrosion resistance
• Fluoroelastomer Internal Seals — chemically resistant to all known fuels, oils, and coolants for reliable, leak-free performance across a wide range of fluid system applications
• Olive Retention System — assembled with an olive that threads onto the double-helix ribbed inner liner of the hose for positive engagement and secure hose end retention
• Reusable Design — engineered for disassembly and reinstallation, making these hose ends a long-term investment for serious builders and race teams

Earl's Performance Plumbing brought aviation fluid transfer technology to the automotive performance market over five decades ago, and top funny car and open-wheel racing teams continue to rely on Earl's today. The UltraPro system was engineered as a complete, integrated solution to exceed the rigorous demands of even the most extreme forms of motorsport — and is equally at home on the street. Available in multiple AN sizes to suit a wide range of high-performance plumbing applications.
