Sierra Male Deutsch Terminal 18-99518 Marine Electrical Connector Pin

The Sierra 18-99518 is a male Deutsch-style terminal used to build and repair marine electrical connections. This terminal pin is designed to mate with a corresponding female Deutsch terminal, forming a secure, weather-resistant connection point within a Deutsch connector housing. It is commonly used by installers and technicians when building custom wiring harnesses, repairing damaged connectors, or replacing a terminal pin that has been bent, corroded, or otherwise damaged in an existing Deutsch connector assembly.

Because it is sold as an individual terminal rather than a full connector kit, the Sierra 18-99518 lets you replace a single damaged pin instead of discarding an entire wiring harness or connector housing. This keeps repairs targeted and cost-effective for boat owners and marine electricians working on engine wiring, trim and tilt circuits, or other Deutsch-connectorized systems commonly found on marine engines and accessories.
