Hole Plugs

Caps and Plugs

Protect the ends of rods, pipe, and tubing to keep debris out.

Hole Plugs for Enclosures

Seal unused holes and knockouts in your enclosures and outlet boxes.

Push the stem into a hole for quick installation. These bumpers are commonly used as feet on instruments and bench-top equipment to keep them from sliding. They're also good as spacers between sheets of material. Also known as stem or grommet bumpers.

Grommets

Reinforce the edges of through holes.

Expansion Plugs

Often used when testing systems for leaks, these plugs expand against the inside of pipes to create a pressure-resistant seal.

Vibration-Damping Grommets,
Bushings, and Washers

Damp vibration and reduce shock inside motors, fans, blowers, actuators, circuit boards, and other electronic equipment.
