Inline Fuseholder Single Waterproof

The American Autowire Inline Fuseholder Single Waterproof is the backbone of reliable electrical protection in marine and automotive wiring systems. Built for boaters, anglers, and off-road enthusiasts who depend on consistent performance in harsh saltwater and wet environments, this single-position fuseholder keeps your critical circuits safe from overload without compromising accessibility. Whether you're running navigation electronics, trolling motor controls, or auxiliary lighting systems, a waterproof inline fuseholder is non-negotiable when your safety and your investment depend on uninterrupted power delivery.

Designed with a fully sealed, waterproof housing, this inline fuseholder protects against corrosion, moisture ingress, and terminal oxidation—common killers of electrical systems on the water. The single-cavity design accepts standard automotive-style fuses and integrates seamlessly into wiring harnesses where space and weight are critical. Compact dimensions (3.8 x 1 x 5.05 inches) and minimal weight (0.05 lbs) mean zero compromise on boat or vehicle performance while delivering robust circuit isolation. American Autowire's engineering ensures the holder maintains solid contact pressure and electrical continuity even after years of thermal cycling and vibration exposure.

Anglers running custom wiring for GPS, sonar, livewells, and high-draw accessories benefit from inline fuseholders positioned close to the power source—exactly where this design excels. Boaters upgrading to lithium batteries, auxiliary chargers, or integrated electrical systems should spec this for any new 12V or 24V protected circuit. Installation requires only basic crimping and heat-shrinking skills; position it within 18 inches of the battery positive terminal or load for optimal protection. This single fuseholder pairs perfectly with American Autowire harnesses and is compatible with most standard fuse amperage ratings, making it an essential component for any marine electrical project where water exposure is unavoidable.
