About Durometer Hardness Scales

Snap these grommets into place to hold wire, cable, and cords in wet locations and form a seal against dust, debris, and water. Two flanges create a seal when pulled through holes in your enclosure, so you can install these grommets without tools. They are made of TPE rubber, which won’t break down under UV exposure. Rated UL 94 V-0, these grommets will stop burning within 10 seconds if ignited.

Grommets with an IP54 rating protect against dust and splashing water from all directions. IP67 rated grommets protect against dust and temporary submersion.

Add a cable tie to grommets with a cable tie attachment point to relieve strain and extend the life of your cable, wire, and cords. These grommets also have closed front sides, so they can be used as hole plugs.
