Earl's Performance UltraPro Straight Twist-On AN Hose Ends

Earl's Performance UltraPro Straight Twist-On AN Hose Ends are precision-engineered companion fittings for Earl's UltraPro Series convoluted PTFE-lined hose, delivering race-proven fluid connection performance for the most demanding high-performance and motorsports plumbing applications. Designed exclusively for use with Earl's UltraPro Series hose, these hose ends are perfectly matched to the system's performance characteristics — built to withstand harsh environments, brutal vibration, extreme pressures, and high-flow requirements across fuel, oil, and coolant circuits.

Premium Materials and Construction:

• High-stress components machined from ultra high-strength 2024-T8 aluminum — a significant upgrade over the 6061-T6 aluminum commonly used by competitors
• Fluoroelastomer internal seals provide superior chemical resistance to all known fuels, oils, and coolants
• Furnace-brazed bent tube construction ensures a permanent, robust bond and unmatched flow at every connection
• ANO-TUFF™ black hard-coat anodizing penetrates deep into the aluminum surface for extraordinary corrosion resistance inside and out, including thread protection against galling
• Weight-optimized geometry on nuts, sockets, and swivels eliminates unnecessary mass without sacrificing structural integrity

Twist-On Assembly Advantages:

• An olive threads onto the double-helix ribbed inner liner of the UltraPro hose for positive engagement and secure hose retention
• Straight configuration provides clean, direct-line routing compatible with a wide range of plumbing layouts
• Reusable and reassemblable — no crimping machine or specialized tooling required
• Selected hose ends incorporate Earl's Dynamic Swivel™ technology, enabling 360° rotation of an installed line for simplified routing and reduced hose stress

System Compatibility:

• Engineered exclusively for use with Earl's UltraPro Series convoluted PTFE-lined hose
• Multiple AN sizes available to accommodate a wide range of high-performance plumbing needs
• Suitable for fuel, oil, and coolant systems in street performance, strip, and professional competition environments

Important: All UltraPro hose assemblies must be pressure tested prior to use.
