Grommets reinforce and protect materials used in the electronics industry such as cables, wiring, connectors, circuit boards and sensitive components. They guard against abrasion, provide strain relief, vibration damping and electrical insulation, and seal openings from ingress of dust, moisture, water and insects.
In China, they are widely available in variants made of natural or synthetic rubber, nylon or stainless steel, with those based on the first two materials forming the bulk of shipments of the majority of suppliers.
Chinese companies continue to highlight their flexibility to customization on materials and their sources, shapes, sizes and tolerances, operating temperatures and other requirements while ensuring UL-listed, CE-marked and RoHS-compliant grommets. They keep initiatives going to achieve high product reliability and life span.
For materials, these manufacturers usually source from domestic providers. There have been no recent changes in input costs, and this is expected to persist in the coming months and keep grommet prices at current levels.
Globally, the market for electronics grommets will continue to thrive, driven by demand in automotive, consumer electronics and industrial applications.
EPDM grommets used in the electronics, automotive, industrial and manufacturing, household and other industries had an estimated value of $723 million in 2025, according to QY Research. This is forecast to reach $1.107 billion in 2032, posting a CAGR of 6.4 percent from 2026.
