#6 Econo-O-Fit Red 9/16

The #6 Econo-O-Fit Red 9/16 from EARLS is a compact worm-gear hose clamp designed for 6 AN applications, which corresponds to a 3/8-inch inner diameter for hydraulic and fuel lines. This economy-grade clamp serves mechanics, fabricators, and motorsports enthusiasts who need reliable line securing on custom fuel systems, hydraulic brake lines, and cooling circuits.

Constructed from lightweight red anodized aluminum, the #6 Econo-O-Fit features a worm-gear drive mechanism with a hex head for easy tightening. The aluminum body resists corrosion in engine bays and fuel tank environments, making it ideal for weight-conscious applications. The 9/16-inch hex head accepts standard socket and wrench tools, enabling quick installation and adjustment without special equipment.

This clamp excels in tight-space engine compartments, aftermarket fuel injection retrofits, and radiator recirculation lines where precision and compact footprint matter. It is compatible with all standard 6 AN hose barbs and pairs seamlessly with braided stainless hose and silicone fuel lines, making it an essential consumable for anyone assembling or maintaining performance or classic vehicle plumbing.
