This rubber firewall plug seals unused 7/8 inch (22 mm) holes in 1/16 inch (2 mm) vehicle
panels. It snaps in for a flush, OEM-style finish on firewalls, body panels, and floor pans
during repair and restoration work.
The flexible silicone rubber absorbs vibration and resists tearing during installation. It

panel cleanup. Designed for MRO teams and technicians working in inch and metric systems.
