Rubber grommets are one of the most common types of grommets and are used across a wide range of industrial applications. Due to their many advantages, various industries use rubber grommets in all kinds of equipment, ranging from vehicles to consumer electronics and more. Here, we will discuss rubber grommets as well as their many benefits and applications.

What Is a Rubber Grommet?

Rubber grommets are used in various manufacturing and electrical engineering applications to cover sharp edges. Also known as insulating bushings, edging, bushings, or eyelets, rubber grommets are typically black in color and can be used for various purposes, including:

  • Protecting wires. Rubber grommets are waterproof and dustproof, and they can protect wires from being easily cut by sharp plates and edges.
  • Strain relief. Rubber grommets can provide strain relief by gripping wires in place and minimizing any damage or disruptions that happen if the cable or cord is accidentally pulled.
  • Aesthetic purposes. Rubber grommets can enhance the appearance of a drilled or punched hole.


What Are the Benefits of Rubber Grommets?

Rubber grommets offer various benefits that make them an ideal solution for numerous applications. Not only do they protect wires and cables from sharp edges but also from the effects of vibration. Other benefits include:

  • Various size options. Rubber grommets come in hundreds of stocked sizes to accommodate varied hole sizes and panel thicknesses.
  • Water-resistant. Rubber grommets offer excellent water-resistant characteristics and are capable of withstanding organic acids and most modern chemicals.
  • Durability and versatility. The durable and resistive properties of rubber grommets make them suitable for a range of industries that may come into contact with harsh conditions. They are built to be long-lasting and won’t come loose as easily as other grommet types.
  • Material choices. Depending on the environment in which the rubber grommets will be used, they are available in several material options, including SBR, Buna-N, EPDM, silicone, Viton, and neoprene.


What Are the Common Applications of Rubber Grommets?
