3 mm Double-Sided Rubber Grommets

These black rubber grommets have a 3 mm inner diameter and a 6 mm outer diameter. They are designed to protect wires from chafing against drilled holes and sharp sheet metal edges. The double-sided design and 1.5 mm groove width allow them to seat securely in panels. Each pack contains ten pieces for multiple installations.

For cable protection in panels and enclosures

Suitable for anyone running new wiring through body panels or replacing cracked grommets in automotive, marine or general fabrication work. The 4.5 mm thickness fits standard panel gauges. Not suited for buyers who need larger bore sizes for thick cable bundles or high-temperature rated materials for engine bay routing.

Check panel thickness and hole size before ordering

Verify that your drilled hole matches the 6 mm outer diameter and that the panel thickness is compatible with the 4.5 mm overall grommet thickness. Ensure the 3 mm inner diameter suits the wire gauge you intend to protect. Confirm the 1.5 mm groove width aligns with your panel edge profile for a secure fit.

Questions about this item

What panel thickness do these 4.5 mm grommets fit?

The grommets have a groove width of 1.5 mm, so they suit panels roughly that thick.

Will the 3 mm inner diameter accept the cables I already use?

The 3 mm (0.118") hole fits wires up to that diameter; measure your cables to confirm.

How can I check the grommets are seated correctly after installation?

Each grommet should sit flush on both sides of the panel with the groove fully engaged and no visible gap.
