Earl's Performance Auto-Fit 120 Degree AN Hose End Fittings

The Earl's Performance Auto-Fit 120 Degree AN Hose End series delivers professional-grade performance plumbing with a smarter, more accessible approach than traditional Swivel-Seal designs. Purpose-built for builders and fabricators who demand reliable, leak-free connections without unnecessary complexity, these fittings offer a compelling combination of ease of assembly and long-term durability.

At the core of the Auto-Fit design is a unique barbed nipple system that pushes directly into the hose rather than threading on. This eliminates the spiral leak path common to conventional single-nipple hose ends. The hose is firmly compressed between the nipple and socket, creating a positive, mechanical seal that holds under demanding real-world conditions.

Key Features:

• Barbed nipple design eliminates the spiral leak path found in conventional hose end fittings
• Hose compressed between nipple and socket for a positive, leak-free mechanical connection
• Machined from high-quality aluminum alloy with a military-spec hard anodized coating for superior wear and corrosion resistance
• Hard anodizing penetrates the aluminum surface for lasting protection — not just a surface coating
• 120-degree angle configuration provides excellent routing flexibility in confined or complex plumbing layouts
• Precision-machined to tight tolerances for consistent, trouble-free installation
• Backed by over 40 years of aerospace heritage using the proven nipple-and-cutter design
• Available in multiple AN sizes to suit a variety of hose and system requirements

Earl's Auto-Fit hose ends are designed for use with Earl's Perform-O-Flex, Pro-Lite, and Auto-Flex hoses, ensuring optimal compatibility and sealing performance across the product line. Whether you're building a performance street car, track vehicle, or custom fabrication, the Auto-Fit 120 Degree series delivers the precision and reliability that Earl's Performance is known for worldwide.
