Protect Unused NMEA 2000 Ports from Dust and Moisture
The Ancor NMEA 2000 Female Blanking Cap covers open female ports on tee connectors, backbone fittings, and other NMEA 2000 network components — keeping dust, moisture, and salt air out of unused connections. Whether you’re planning to expand your network later or simply have spare ports that won’t be used, these caps maintain the integrity of your network connectors and prevent corrosion at the contact points.
Sold as a 2-pack, providing coverage for two unused female ports.

🔧 Parts Desk Insights
Best use case: These blanking caps are an easy-to-overlook but important part of a clean NMEA 2000 installation. Any unused female port on a tee connector or backbone fitting is an open path for moisture and salt air — which will corrode the contacts over time and cause intermittent network faults. Cap every unused port at installation, even if you plan to add devices later. The 2-pack is well-suited for a single tee connector with one spare port, or two separate locations on the network. If you’re building a new network from scratch, start with a Starter Kit and add blanking caps for any unused tee ports.
