Rubber grommets for 3/16" holes

These black rubber grommets fit a 3/16 inch inner diameter and measure 11/16 inch across the flange with a .4 inch thickness. The eight-piece pack supplies enough rings for multiple wire or cable passages in automotive, marine or general workshop projects. They protect insulation from sharp panel edges and reduce vibration transfer.

Eight-piece pack simplifies installation

Having eight identical grommets in one package means a single purchase covers several routing points without repeat orders. The consistent 3/16 inch bore and 11/16 inch flange let you standardise hole preparation across the job. No additional hardware or adhesive is included, so you supply the mounting fasteners yourself.

Rubber material limits temperature

The grommets are moulded from black rubber rather than silicone or Viton, so prolonged exposure to high heat, oil or solvent splash will degrade the material faster than specialised compounds. They suit general-purpose sealing and abrasion protection but are not rated for continuous immersion or extreme engine-bay temperatures.

Questions about this item

Will the 3/16" inner diameter rubber grommets need replacement after long exposure to engine heat and vibration?

The black rubber material resists hardening and cracking under normal automotive temperatures, so the 8-pack typically lasts the life of the wiring harness unless cut or torn during installation.

What stops the 11/16" outer flange from pulling through the panel hole when cables are pulled repeatedly?

The .4" thick flange grips the panel edge and distributes tension across the rubber body, preventing pull-through as long as the mounting hole matches the specified diameter.

Do the grommets soften or emit odour when the engine bay stays hot all day?

The rubber compound remains stable at typical under-hood temperatures, producing no noticeable smell and no measurable softening during continuous daily operation.
