Newmar PX-1 Junction Box

The Newmar PX-1 Junction Box is a marine-grade waterproof enclosure designed for boaters and marine electricians who need reliable connections in harsh saltwater environments. Built to withstand the corrosive spray and moisture exposure inherent to on-water installations, this junction box simplifies wiring distribution both above and below deck. Whether you're upgrading galley systems, managing battery banks, or consolidating navigation circuits, the PX-1 provides a weatherproof solution where conventional boxes fail.

The Newmar PX-1 features molded nylon construction that resists UV degradation and saltwater corrosion, with pre-installed connector strips that accommodate screw-terminal connections for secure, vibration-resistant wiring. This design eliminates exposed terminals and loose connections that commonly fail on vessels exposed to constant motion and spray. The compact footprint—weighing just 1 pound—makes it easy to mount in tight cabin spaces or engine compartments without adding unnecessary weight to your electrical distribution system. Pre-installed pairs of connectors standardize the connection interface and reduce assembly time during installation or troubleshooting.

Cruisers, fishing boat owners, and marine technicians depend on the Newmar PX-1 for applications where conventional plastic boxes deteriorate within seasons. The waterproof rating makes it ideal for bow rail systems, swim platform wiring, and any circuit prone to spray and humidity. Installation is straightforward with standard through-deck or bulkhead mounting, compatible with most 12V and 24V DC marine electrical systems. For boaters seeking reliable, maintenance-free junction solutions that withstand years of saltwater exposure, the PX-1 delivers proven durability and peace of mind.
