Garmin Flush Mount Gasket f/GNX™ 120

The Garmin Flush Mount Gasket for GNX 120 is an essential installation component for boaters and anglers who demand a clean, professional integration of their marine electronics. Whether you're mounting a chartplotter, fishfinder, or integrated navigation display on your boat's dash or console, this gasket ensures a watertight seal against flat surfaces while maintaining the sleek, recessed appearance modern boat owners expect. For anyone running a GNX 120 system, proper mounting hardware isn't optional—it's the foundation of reliable performance on the water.

Designed specifically for Garmin's GNX 120 unit, this flush mount gasket provides a precision-engineered seal that prevents water intrusion, salt spray, and vibration-induced loosening during extended time underway. The gasket's engineered material handles the thermal cycling common in marine environments—expanding and contracting with sun exposure and cooling without degrading. At 1.5 pounds and compact dimensions of 4 x 4 x 8 inches, the gasket is lightweight yet robust enough to support secure mounting on most flat boat surfaces, from fiberglass consoles to aluminum frames.

This gasket is ideal for professional fishing guides, recreational boaters, and anyone with a GNX 120 who wants to protect their investment and eliminate water leaks around the mounting perimeter. Installation is straightforward—position the gasket between the unit and your mounting surface, then secure according to Garmin's fastening specifications. If you're upgrading, replacing a worn seal, or installing a new GNX 120 system, having the correct Garmin gasket on hand ensures your electronics stay dry and your display stays operational, season after season on saltwater or freshwater.
