Grommets have a universal application and therefore represent great accessories in various industries. You can find them under different names, but they all refer to attachments that help protect wires and cables, and are also used to dampen the vibrations that occur during the operation of industrial machines. Aerospace, shipbuilding, medicine and the electronics industry, and mechanical engineering are just some of the areas where you may notice frequent use of grommets.

They are made of materials such as plastic, metal and rubber, and also in different dimensions, shapes and designs, so that they can sometimes be a significant aesthetic addition to home appliances. In the automotive industry, so-called firewall grommets are often used, which play an important role in vehicles. They are placed around wires and cables that pass through the car’s firewall or body panel. Firewall grommets in this case protect the cables from sharp sheet metal that could damage them.

Although plastic ones can also be used, rubber firewall grommets have shown better general characteristics and greater power to protect the wires from the impact of the surrounding parts. If these wires are not adequately insulated, they can permanently wear out and lose their function, or lead to a short circuit and damage to the electronics. And if you have equipped your car with a new, expensive stereo device, the last thing you want is for permanent insulation to permanently damage it just because you didn’t pay attention and invest in quality firewall grommets.

Plastic grommets break much more easily or fall off the cables, leaving them unprotected and exposed to the mechanical force of the surrounding metal parts of the body. The use of rubber firewall grommets prevents such unwanted events. When choosing firewall grommets in order to optimally protect your vehicle, make sure that they are designed to best meet all specifications in the automotive industry.
