Featured Products

These black rubber hole plugs are designed for sealing unused holes in automotive
firewalls, body panels, and sheet metal openings. The push-in compression stem
creates a secure friction fit across a wide range of hole sizes from 7/8" to 2-1/2"
(22–64 mm), making them ideal for repair, restoration, and panel finishing work.

The flexible rubber construction provides a tight seal against dust, moisture, and
debris while preventing vibration and metal-to-metal contact. The flush-mount head
delivers a clean finished appearance while maintaining reliable retention in thin
and thick panel materials commonly found in automotive and fabrication settings.

Used by auto body shops, restoration technicians, and powersports repair teams,
these plugs are suited for vehicles, trailers, and equipment panels in both indoor
and outdoor environments. Designed for MRO teams and technicians working in inch
and metric systems.
