Purpose and fit
These black rubber blind grommets seal 40 mm panel openings to protect cables from sharp metal edges. The pack contains five pieces for automotive or general wiring jobs where a finished hole must stay watertight and abrasion-free.
Behaviour under load
The 38 g rubber construction stays flexible across temperature swings and resists cracking when panels vibrate. Each grommet grips the hole firmly without adhesive, so cables remain shielded during long drives or machinery operation.
Build and daily use
Single-sided flanges sit flush on one face for a clean look and simple push-in fitting. The 29.5 mm inner diameter, 47 mm outer diameter and 6.5 mm thickness suit standard sheet-metal gauges and allow quick replacement of worn seals.

Questions about this item
Will the 29.5mm inner diameter fit the same wiring harness I use with my current 40mm grommets?
The inner diameter is 29.5mm while the outer diameter is 47mm; your harness must be smaller than 29.5mm to pass through this grommet.
Do I need any adhesive or tools to install these rubber grommets in my panel?
No adhesive or special tools are required; each grommet presses into a suitably sized hole by hand.
Can these grommets replace the cracked 40mm units already in my vehicle's body panels?
Yes, the 47mm outer diameter and 6.5mm thickness are designed to seat in standard panel cut-outs for wire protection.
