What These Grommets Do
Black rubber grommets protect wiring, hoses or tubing where they pass through metal or plastic panels. The 1-3/16 inch inside diameter fits common automotive and industrial bundles, and the 1/4 inch groove depth seats in standard sheet-metal thicknesses. Mechanics, fabricators and DIY restorers use them to prevent chafing and vibration damage.
Installing and Common Issues
Push the grommet into a clean, deburred hole until the flange sits flush; a light coat of silicone spray eases insertion without degrading the rubber. Problems arise when the panel is thicker than the 1/4 inch groove or when the hole is oversized, letting the grommet pull through under vibration. Sharp hole edges can also slice the rubber during installation.
Limits of the Rubber Seal
Natural rubber resists water, mild detergents and occasional oil splash, but it swells and cracks with sustained fuel, solvent or high-temperature exposure. The material softens above typical under-bonnet temperatures and hardens in deep cold, so it is not suited for continuous immersion, pressurised lines or direct exhaust heat. UV exposure will eventually dry-rot the surface.

Questions about this item
How can I verify the grommets fit correctly after installation?
Check that the 1-3/16" inner diameter seats the wire or tube snugly, the 1-11/16" outer flange sits flush against the panel, and the 1/4" thickness with 1/16" wall fills the cut-out without gaps.
What comes in the package and what must I supply myself?
The box contains black rubber grommets model 64375; you must provide the mounting panel, a correctly sized hole cutter, and any wiring or tubing to pass through.
Which size should I choose for a 1-3/16" hole?
Select the 64375 grommet — its 1-3/16" inner diameter matches that hole, while the 1-11/16" outer diameter and 1/4" panel thickness cover the cut-out.
