Rubber Grommets

Rubber Grommet ManufacturerMinor Rubber manufactures a wide assortment of high-quality rubber grommets to fit most industrial applications. We maintain an extensive inventory in various sizes and materials to meet your specific requirements. Many styles are available in more than one material or durometer hardness.

What are 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, 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.

Specification Grades

Most of our stock grommets are made from Buna-N (Nitrile), however, we also manufacture custom grommets in a range of materials. For example, we use commercial grades of SBR, silicone, Neoprene® 1, and EPDM. Materials are available in commercial and specification grades including NASM 3036 Composition A and B, Mil-Spec, ASTM, AMS, SAE, and others.
