Food-grade silicone rubber grommets engineered for high durability, waterproof and dustproof sealing, and reliable vibration damping in electronic equipment panels and industrial enclosures.
We supply grommets in a broad range of polymers, including NBR, NR, EPDM, FKM, SBR, silicone, and neoprene. Custom material formulations are available on request. If you are unsure which compound suits your application, describe your operating conditions and our team will recommend the appropriate material.
Each material offers distinct advantages. Depending on the selected compound, grommets deliver high temperature resistance, oil resistance, abrasion resistance, aging resistance, and corrosion resistance to match demanding industrial environments.
We produce rubber grommets in a wide range of shapes, sizes, and specifications, including MIL-spec grommets, compressor grommets, web grommets, and blind grommets. The high durability and resilient quality of our rubber grommets make them suitable for use across multiple industries and demanding operating conditions.
