Always verify clamp dimensions, hose material, fitting requirements, and suitability for the intended fuel or fluid system before installation.
Measure the outside diameter of the hose after it has been fitted to its connection. Select a clamp that matches the measured diameter and the manufacturer's sizing recommendations.
Ear clamps are generally designed for one-time crimp installation using suitable ear-clamp pincers. Follow the clamp manufacturer's installation instructions to achieve the intended fit.
Important: Do not select a clamp based solely on the nominal hose diameter. The required clamp size depends on the installed hose and fitting dimensions.
Select your preferred kit configuration from the available product variants.
Clamp quantities and sizes are as specified above.
Pincers are included only with the applicable tool-kit variants.
Storage case configuration depends on the selected option.
