Product Overview

Maintain the safety and functionality of your vessel’s fire suppression and detection systems with this 3″ Clear Rubber Inner Diaphragm. Specifically designed as a replacement insert for marine fire port assemblies, it preserves a sealed barrier to prevent the spread of flames, smoke, or vapors—while its transparent material allows unobstructed inspection of the port’s interior.

This diaphragm press-fits or snaps into place within compatible 3″ fire port housings and flexes during fire extinguisher discharge, allowing nozzle access without removing the port body. It’s an essential part for ensuring rapid response and maintaining visibility in marine fire safety systems—offered as a standalone replacement component (fire port housing and trim ring not included)
