Earl's Performance Auto-Fit 180 Degree AN Hose Ends

Earl's Performance Auto-Fit™ 180 Degree AN Hose Ends deliver race-proven reliability backed by decades of aerospace engineering expertise. Founded in 1955, Earl's Performance pioneered the performance plumbing industry, creating many of the hose end designs and standards the motorsport world still depends on today. The Auto-Fit™ line carries that legacy forward with a design that is faster to assemble and more cost-effective than traditional swivel-style hose end solutions.

The Auto-Fit™ Advantage:

Conventional single-nipple hose ends thread into the hose, creating a potential spiral leak path as part of the seal. The Auto-Fit™ design eliminates this risk entirely. The barbed nipple is pushed — not threaded — into the hose, and the hose is then compressed between the nipple and socket, sealing positively at the barbs. The result is positive hose retention with no spiral leak path, underpinned by a nipple-and-cutter system that has been aerospace-proven for over 40 years.

Key Features:

• No-spiral-leak-path design — barbed nipple seals by compression, not threading, for a more secure and reliable connection
• Positive hose retention on par with Earl's premium Swivel-Seal hose ends
• Aerospace-grade aluminum alloys that meet or exceed minimum aerospace hose end requirements (aluminum variants)
• Military-spec hard anodized coating that penetrates the aluminum for superior wear and corrosion resistance (aluminum variants)
• Stainless steel variants available for maximum corrosion and temperature resistance in marine, chemical, or exotic fuel applications
• Precision-machined to exacting tolerances for consistent, trouble-free performance
• 180-degree U-turn configuration engineered for tight, complex, or space-constrained plumbing layouts
• Faster and easier assembly compared to conventional threaded hose end designs
• Reusable construction for lasting value and easy system modifications
• AN (Army-Navy) thread standard for broad compatibility across performance plumbing systems

Earl's Auto-Fit™ hose ends are engineered exclusively for use with Earl's Perform-O-Flex™ and Auto-Flex™ hose to ensure optimal sealing, retention, and pressure performance. Available in multiple AN sizes and in both aluminum and stainless steel construction — choose the material that best suits your application's requirements for weight, temperature resistance, and corrosion protection.
