Cole Hersee 2 Pole Plug & Socket Connector w/Rubber Cap

The Cole Hersee 2 Pole Plug & Socket Connector with Rubber Cap is a marine-grade electrical connector engineered for reliable power distribution in demanding boating and marine applications. After years running boats and working on docks, you learn quickly that connector quality directly impacts safety and uptime on the water. This polarized connector pair ensures correct polarity every time, eliminating the risk of reversed connections that can damage sensitive electronics or shore power systems. Whether you're wiring a new boat, upgrading bilge pump circuits, or adding auxiliary power distribution, a solid two-pole connector is foundational infrastructure.

Cole Hersee has built its reputation on marine connectors that withstand saltwater exposure, vibration, and corrosive environments where standard electrical components fail. This assembly ships complete with both male and female connectors—a finished pair ready for your specific application once leads are inserted and terminated to your boat's wiring specifications. The included rubber cap protects the socket when not in use, sealing out moisture and salt spray that would otherwise corrode contacts. The polarized design is the critical detail: only one orientation allows connection, so even under deck in poor lighting, you cannot accidentally reverse polarity and fry electronics worth thousands of dollars.

Boaters upgrading shore power systems, installing secondary batteries, or adding independent circuits for pumps, lights, and navigation equipment rely on connectors like this to isolate power distribution and allow quick disconnect when hauling or winterizing. The compact footprint (2 × 1 × 3 inches) fits tight engine compartments and console installs without taking up valuable real estate. Professional installers and DIY riggers both choose Cole Hersee for repeatability—once you've terminated one connector, the next goes faster, and you know the quality is consistent across every circuit on your vessel.
