Electrical rubber grommets line the hole where wire passes through sheet metal, panels, firewalls and enclosures, so sharp edges cannot cut the insulation. We stock 9 black rubber snap-in sizes from 1/8" to 1" inside diameter for automotive, marine, trailer and control-panel wiring.
| Inside diameter (wire passes through) | Outside diameter |
|---|---|
| 1/8" | 11/32" |
| 3/16" | 7/16" |
| 1/4" | 9/16" |
| 5/16" | 9/16" |
| 3/8" | 5/8" |
| 1/2" | 1-1/6" (about 1.17") |
| 5/8" | 1-1/8" |
| 3/4" | 1-3/8" |
| 1" | 1-3/4" |
Our rubber grommet size chart walks through all three measurements.
No. These are snap-in grommets: push the grommet into the hole so the panel edge seats in its groove.
ID is the hole the wire goes through; OD is the overall outside size of the grommet.
Yes — grommets are commonly used where wiring passes through firewalls, body panels and bulkheads. Check the temperature rating on the listing for hot locations.
