Ancor Marine Grade Electrical Wire Seal - Flat Cable, 14/3 to 12/3 AWG, 1/2" NPT

The Ancor Marine Grade Electrical Wire Seal for flat cable (14/3 to 12/3 AWG, 1/2" NPT) is a UL and CSA-approved liquid-tight cable entry connector designed for watertight sealing in marine electrical panels and junction boxes. This connector provides reliable, low-cost protection for electrical connections exposed to saltwater, fuel, and harsh offshore environments.

The seal accommodates flat cable between 14/3 and 12/3 AWG, with a 1/2-inch NPT fitting that integrates into standard marine electrical panels. The connector is resistant to saltwater corrosion, gasoline, alcohol, ketones, and mineral oil—critical attributes for boats operating in coastal or offshore conditions. It maintains a watertight seal to depths of 300 feet (150 PSIG), making it suitable for subsurface electrical installations on research vessels, commercial fishing boats, and deep-diving support craft.

This product serves weekend recreational boaters and serious commercial fishing operations alike. Weekend anglers upgrading electronics, fish finders, or navigation systems benefit from the simplified installation and chemical resistance. Commercial and offshore operators appreciate the dual certification (UL/CSA), proven reliability under extreme pressure, and resistance to the combination of saltwater spray, fuel spills, and the thermal cycling common in marine engine rooms. The NPT fitting standard ensures compatibility with existing marine electrical infrastructure.

Marine electrical failures due to water intrusion remain a leading cause of mid-voyage system loss. The liquid-tight design of Ancor's wire seal eliminates the vulnerable gap where flat cables pass through panel walls, preventing moisture migration and corrosion at connection points. Its proven chemical compatibility and pressure rating make it a standard component in shipboard electrical retrofits and new-build marine systems where code compliance and durability are non-negotiable.
