Earl's Performance Auto-Fit™ 150 Degree AN Hose End

The Earl's Performance Auto-Fit™ 150 Degree AN Hose End line delivers professional-grade plumbing performance at a value-conscious price point. Engineered to provide the reliability and appearance of Earl's legendary Swivel-Seal™ hose ends, the Auto-Fit™ series is designed for easier assembly — making it the ideal solution for racers, builders, and performance enthusiasts who demand quality without compromise.

Patented Barbed Nipple Technology:

Unlike conventional threaded nipple designs — where the thread itself forms part of the seal and creates a potential spiral leak path — the Auto-Fit™ features a patented barbed nipple that pushes directly into the hose rather than threading in. The hose is compressed between the nipple and socket, sealing positively at the barbs with no spiral leak path. This aerospace-proven approach delivers the same positive hose retention as Earl's premium Swivel-Seal™ fittings.

Key Features:

• Aircraft-quality aluminum alloy — precision-machined to meet or exceed aerospace hose end requirements
• Military-spec hard anodized coating — penetrates the aluminum for superior wear and corrosion resistance
• Single barbed nipple, non-adjustable fixed-position design — ideal for permanent plumbing installations
• 150-degree angle — engineered for tight, clean routing in confined engine bays and chassis plumbing runs
• Suitable for oil, coolant, fuel, and a wide range of automotive and racing fluid system applications
• Available in multiple AN sizes and finish options to suit various plumbing configurations

Hose Compatibility:

Earl's Auto-Fit™ hose ends are engineered specifically for use with Earl's Perform-O-Flex®, Pro-Lite 350, Pro-Lite Ultra, Pro-Lite 390, and Auto-Flex™ hose lines. For guaranteed sealing integrity and maximum performance, use exclusively with compatible Earl's hose products.

Earl's Racing Heritage:

Earl's Performance has been at the forefront of motorsport plumbing since 1955, bringing aviation-grade fluid transfer technology to the racing world. Earl's invented the self-indexing Swivel-Seal™ hose end in 1973 and pioneered the flexible armored PTFE-lined hose for motorsport use. Top funny car, sprint car, and Indy car teams continue to rely on Earl's plumbing — with Earl's appearing on the vast majority of Indy 500 winners. The Auto-Fit™ line carries that same legendary heritage into an accessible, easy-to-assemble product family.
