NMEA2000 - J1939 (All Brands) - Cable Cap
When space is limited, don't leave your cables exposed to saltwater and corrosion. The ProTek Cable Cap provides a secure, watertight seal — protecting the ends of your cables from water ingress, salt buildup, and the long-term damage that follows.
Each cap features precision-matched threads for a tight, reliable fit, and a durable lanyard that keeps the cap attached when it's not in use — so you never lose it overboard or in the engine bay.
Sold Individually and in kits of 8, and specifically designed to suit cables from Garmin, Lowrance, Simrad, Humminbird and Furuno.
