What are Rubber Grommets? industrial rubber grommets

Grommets are useful in electronics applications when a wire or tube needs to pass through metal or another material that may cause damage. Most commonly, they protect cables from sharp corners and edges.

We offer standard insulation grommets in Buna-N (Nitrile), and we also manufacture Mil-Spec grommets for military applications, vibration mount grommets to protect components from noise & vibration, and other specialty grommets. Grommets can be pushed into place using our grommet inserter tools. For more information on any of our rubber grommets, including Buna-N (Nitrile) grommets, contact us today!
