200 double-sided rubber grommets for wire protection

This pack supplies 200 double-sided rubber grommets designed to protect cables and pipes passing through metal panels. The black rubber material suits industrial and anti-vibration uses across automotive and electrical projects. Buyers needing a large quantity of consistent grommets for panel cut-outs will find the count practical. This product is not for users who require adhesive-backed or flanged grommets for surface mounting.

8 mm outer diameter with 3 mm inner bore

Each grommet measures 8 mm outer diameter and 3 mm inner diameter with a 4.5 mm thickness, fitting standard panel holes for wire routing. The rubber construction absorbs vibration and prevents abrasion on cable insulation during daily operation. The lightweight 27 g total pack weight makes storage and handling easy on the workbench. Installers who need snap-in retention or integrated strain relief will not find those features here.

Replaces worn or missing panel grommets in harness

These grommets replace damaged or missing rings in existing wiring harnesses and panel assemblies. The 200-piece quantity supports full loom rebuilds or multiple vehicle restorations without reordering. The jump is worthwhile when a project demands uniform black rubber grommets in bulk for through-panel protection. Buyers needing metric sizes other than 3 mm inner diameter should source a different kit.

Questions about this item

What is the outer diameter of these grommets and what panel hole size does it suit?

The outer diameter is 8mm (0.3") and the grommet body is 4.5mm (0.18") thick, so it fits a panel cut-out of roughly 8mm.

What are the exact dimensions I need to check before drilling the mounting holes?

Each grommet has an 8mm outer diameter, a 3mm inner diameter for the wire, and a 4.5mm flange thickness that seats against the panel.

How do I install these double-sided grommets without tearing the rubber?

Push the grommet into the 8mm hole from one side until the 4.5mm thick flange seats flush, then feed the cable through the 3mm centre.
