Overview

The i2Systems 7120132 is a closed-cell foam gasket used when installing Aperion Series lights to help seal the light flange against the mounting surface and keep water from tracking behind the fixture.

Closed-cell foam compresses to fill small surface texture and fastener gaps, which helps on hardtops, spreaders, cabin sides, and other areas that see spray and washdowns. It is sold as a single gasket (shipping weight about 0.1 lb).

Key features

• Made to match i2Systems Aperion Series light mounting footprints for a consistent seal at the flange
• Closed-cell foam resists water absorption and stays springy after compression
• Helps reduce water intrusion behind the light, which can lead to staining around the trim and corrosion at fasteners
• Useful on slightly curved or lightly textured mounting surfaces where a bare flange can leave small leak paths

Installation and setup

Dry-fit the gasket with the light to confirm hole alignment, then clean the mounting area so the gasket seats flat. Tighten fasteners evenly so the foam compresses all the way around without bunching. If the light is removed for service, replace the gasket if it is torn, permanently flattened, or contaminated with old sealant.

Compatibility and fit

This gasket is intended for i2Systems Aperion Series lights. It is a good match for boats that live outdoors or get frequent washdowns, where keeping water from wicking behind a deck or spreader light matters.

For the best seal, the mounting surface should be clean and fully supported around the light footprint. On cored panels, make sure the core is properly sealed and the fasteners are bedded per your normal practice.

Maintenance and care

Rinse the area during washdowns and avoid harsh solvents that can degrade foam. If the light starts to move from vibration, re-check fastener tension and the gasket condition.
