  • Protects wires from chafing with 18mm rubber grommets

  • 28mm outer diameter covers drilled holes completely
  • Lightweight 16g pack includes five grommets for multiple installs

Wire Grommets for Cable Protection

These black rubber grommets shield cables from sharp edges in drilled panel holes. The double-sided design fits securely in place to prevent chafing on automotive or sheet-metal installations. A pack of five provides enough pieces for multiple wire-routing tasks. Suitable for electricians and DIYers replacing cracked originals or running new loom safely.

18 mm Inner Diameter for Wire Passage

The critical dimension is the 18 mm opening that determines which cables will pass through. Groove width of 2 mm matches standard panel thicknesses so the grommet seats flush on both sides. Total flange diameter is 28 mm giving a broad bearing surface. Verify your wire bundle and panel cut-out against these figures before ordering.

Rubber Construction Handles Heat and Vibration

The rubber material remains flexible across typical engine-bay and chassis temperatures without hardening. It dampens vibration that could otherwise wear insulation against the hole edge. At 16 g for the full set the parts add negligible mass to the harness. No lubrication or special tools are required for installation.

Questions about this item

How much clearance does the 18mm inner diameter give a wire bundle?

The 18mm inner diameter provides approximately 0.7 inches of clear space for cables to pass through without rubbing the panel edge.

What panel thickness does the 2mm groove width suit?

The 2mm groove width is designed to snap into sheet metal or plastic panels around 2mm thick, locking the grommet in place on both sides.

Will the 28mm outer diameter fit a standard 1.1-inch drilled hole?

Yes, the 28mm (1.1-inch) total diameter matches a 1.1-inch hole, and the 10mm overall height sits nearly flush once installed.
