1/4" rubber grommets for cable protection

The Metra Electronics RG14 rubber grommets insulate and seal wires, hoses or tubing passing through panels. Each grommet has a 1/4" inner diameter, 1/2" outer diameter and 1/4" overall thickness with a 5 mm hole diameter. The black rubber minimises abrasion and dampens vibration in automotive, marine, hot rod, electronics, audio and hobby installations. A pack contains 100 pieces for large or repeated jobs.

Flexible rubber suits indoor and outdoor use

The black rubber material resists weather exposure and fits panels with a 5 mm hole. Installation is straightforward: push the grommet into the cut-out and route the cable through the .25" centre. The snug fit protects conductors from sharp panel edges and reduces rattling caused by vibration. The flexible body conforms to curved surfaces without cracking.

Replaces worn or missing grommets in existing looms

Use this pack when original grommets have hardened, split or been lost during repairs. The 1/4" inner diameter matches many factory wire-loom sizes, so the upgrade restores protection without re-drilling panels. The jump is worth it when a harness shows chafing marks or when adding new cables to an already-grommeted bulkhead.

Questions about this item

What hole diameter does the 1/4" inner-diameter grommet require?

Each grommet fits a 5 mm panel hole; the 1/4" inner diameter protects wires or tubing passing through.

How thick a panel can the 1/4" overall-thickness grommet accommodate?

The grommet body is 1/4" thick, so it seats flush in panels up to that thickness.

How do you seat the grommet without tearing the rubber?

Lubricate the grommet lip, then press it evenly into the 5 mm hole until the flange sits flat — forcing it crooked is the common mistake.
