Grommets

Grommets

GROMMETS: These are used for protection of cover hole, a wire, tube, or various other objects from abrasion when they are passed through metal, plastic, or any material that could damage the outside surface of the item while being installed, or when in use. Additional applications include electrical insulation, noise reduction, vibration isolation and protection from forces generated in compression. There are different types of grommets for a variety of applications.

Important size dimensions need to be considered when specifying grommets include inside diameter, outside diameter, thickness or working height, groove thickness and groove depth. We manufacture Rubber Grommets of different shapes & sizes made from a variety of rubber grades like SILICON, EPDM, TPR, NBR, NEOPRENE, SBR & NATURAL. The hardness rating on a Shore A scale for Grommets can be 30 ~ 85 durometer. Exact specifications should be clarified by our engineers, as chemical and physical properties of grommets can differ based on manufacturing technique & application.
