#12 E-Z Clamp Black

The #12 E-Z Clamp Black is a worm gear hose clamp engineered for secure hydraulic and coolant line connections in high-performance automotive applications. Built by FRAGOLA, a trusted name in fuel system and fluid line components, this 12 AN clamp is the go-to fastening solution for mechanics and engine builders who demand reliability under pressure. Whether you're assembling a custom cooling loop, routing fuel lines on a modified engine, or securing hoses in a race car build, the E-Z Clamp delivers consistent clamping force without slip or leakage.

Constructed from aluminum with black anodized finish, this clamp resists corrosion and blends seamlessly into modern engine bays while providing superior durability. The worm gear design allows smooth, progressive tightening that distributes load evenly around the hose perimeter—eliminating hot spots and hose deformation that can compromise system integrity. The 12 AN sizing (0.75-inch ID nominal) fits standard -12 hose, a common spec in fuel injection, turbo cooling, and custom plumbing on street and track builds. Compact at just 0.03 lbs, the clamp adds negligible weight while the anodized aluminum construction ensures it won't rust or seize, even in harsh underbody environments.

Ideal for EFI conversions, turbo kits, fuel cell installations, and radiator or intercooler hose work, this E-Z Clamp is a staple in any serious automotive technician's toolkit. It pairs perfectly with braided stainless or rubber hose for fuel rails, coolant bypass lines, and catch-can systems. Single-clamp order ensures you have exact quantities for your project without waste. For reliability that matches the quality of your lines and fittings, the #12 E-Z Clamp Black delivers straightforward, dependable clamping performance that won't let you down on the street or at the strip.
