12 mm rubber grommets for wire protection

This pack contains 20 black rubber grommets with a 12 mm inner diameter. They are designed to protect cables and wiring from sharp edges when passing through metal panels or firewalls. The grommets suit automotive, RV and marine restoration or wiring jobs. They also reinforce holes in leather, cloth or canvas materials.

Fits 14 mm mounting holes in 2.5 mm thick plates

Each grommet requires a 14 mm mounting hole and fits panel thicknesses of 2.5 mm. The rubber material resists heat, mineral oil and wear for durable sealing. An elastic tolerance of 1 to 2 mm on dimensions should be expected during installation. These limits define the compatible panel preparation and cable sizes.

Replaces worn or missing grommets in existing

Use this set to replace deteriorated grommets that no longer seal or protect wiring in vehicle restorations. The 20-piece quantity covers multiple firewall or panel penetrations in a single project. The upgrade is worthwhile when original grommets have cracked, hardened or been lost during disassembly.

Questions about this item

Should I pick these 12 mm grommets or a different diameter for a 14 mm mounting hole?

Choose the 12 mm inner-diameter version when your panel hole is 14 mm; the grommet is designed to snap into that exact cut-out and grip a 2.5 mm thick plate.

What does the 12 mm inner diameter mean once the grommet is fitted in my panel?

It gives a 12 mm clear passage for cables or wires while the rubber body seals the 14 mm cut-out, preventing chafing against metal edges and keeping out dust and moisture.

Are these grommets rated to a specific IP or UL standard that limits where I can install them?

No formal IP or UL rating is published; they are general-purpose rubber grommets intended for automotive, RV, marine and electrical panel work where a basic seal and abrasion protection are needed.
