Maretron Mini Cap – Male Connector Cover – M65-0086

Protect exposed marine network connections with the Maretron Mini Cap (M65-0086) — a small but essential accessory designed to cover unused male NMEA 2000® or Maretron mini-style connectors. Whether you’re installing a backbone, adding sensors, or expanding your vessel’s network, this mini cap helps maintain signal integrity and system reliability by preventing moisture, salt spray, dust, and corrosion from entering open connections.

Made to fit Maretron’s proprietary mini connector system, the M65-0086 mini cap provides a snug, waterproof seal when male plugs are not in use. It’s an inexpensive but critical component to keep your marine electronic network clean, secure, and performing optimally — especially in harsh saltwater environments where unprotected connectors can degrade quickly.

Whether you’re a professional installer or a DIY boater, adding mini caps during installation ensures your NMEA 2000® network stays watertight and protected for years of service.


Key Features and Benefits

  • Environmental Protection: It provides a watertight seal that protects unused connectors from moisture, salt spray, and corrosion, which are the leading causes of network failure.

  • Physical Security: Prevents dust, dirt, and debris from entering the connector pins, ensuring a clean connection if you decide to expand your network later.

  • Threaded Design: Features a secure threaded coupling that matches standard NMEA 2000 Mini-sized connectors, ensuring it won't vibrate loose even in high-speed or heavy-sea conditions.

  • System Longevity: By keeping the connector pins dry and clean, it prevents electrical shorts and maintains the overall signal integrity of your data backbone.

Summary for the User

If you have an open male port on a Mini-sized Tee or the end of a backbone that isn't currently terminated, the M65-0086 is a low-cost insurance policy for your electronics. It is much more effective than electrical tape, which can leave a sticky residue and fail over time.

Note: Ensure your network is using Mini (large) cabling before purchasing. Most recreational boats use Micro (small) cabling, which would require a different cap.
