Newmar CCX-S Thru-Dex Fitting

The Newmar CCX-S Thru-Dex Fitting is a critical marine electrical component designed for vessel power management systems where reliability cannot be compromised. Built by Newmar Power, a trusted name in marine electrical integration, this thru-deck fitting bridges shore power, generator circuits, and battery systems with the ruggedness required for saltwater and freshwater environments alike. Whether you're running offshore for days or moored in a home marina, a properly installed CCX-S ensures safe, corrosion-resistant power distribution without voltage drop or connection failure.

The CCX-S delivers the Thru-Dex design philosophy: a through-deck connector that isolates marine systems from moisture infiltration while maintaining low-impedance contact surfaces. This fitting uses precision engineering to prevent oxidation and galvanic corrosion, common failure points in older through-hull installations. The sealed connector housing protects internal contacts from salt spray, rain, and spray-over conditions, while the integrated deck seal eliminates the need for secondary waterproofing tape or sealant workarounds. Weighing just 1 pound, it's compact enough for tight cabin or engine room routing without adding unnecessary weight to your electrical backbone.

Boaters upgrading legacy electrical systems or installing new inverter/charger circuits benefit most from the CCX-S, particularly those retrofitting dual-bank charging or shore-power isolation. Installation requires a clean through-deck hole and compatibility with your vessel's wire gauge and terminal type—confirm your existing Newmar system specifications or consult your boat's electrical schematic before ordering. The fitting integrates seamlessly into Newmar's comprehensive power management ecosystem, making it ideal for anyone already running a Newmar bank selector, battery monitor, or integrated power center.
