These solid rubber panel plugs are designed to seal 1\" (25 mm) holes in 1/8\" (3 mm) auto body and sheet metal panels. The snap-in grooved retention design provides a flush, finished appearance while locking securely into knockout holes.
They prevent dust, moisture, and debris from entering body panels and firewall openings while restoring a clean factory-style look. The non-conductive rubber construction also reduces vibration and eliminates metal-to-metal contact in panel applications.
Common in auto body repair, restoration work, and sheet metal fabrication where unused holes must be sealed cleanly and permanently. Designed for MRO teams and technicians working in inch and metric systems.
