There are many different types of small protective units that are utilized in many industries, and the rubber blanking grommets are one of the most popular choices amongst users. Not many people are aware what is the purpose of these units, and as manufacturers, we can tell you that the rubber blanking grommets are most commonly used in the automotive field. Even though they find their purpose in other industries as well, they are usually implemented into vehicle panels, wings, and tailgates. They come in different shapes, but the most common one they are manufactured in is circular. Note that if you need a custom design of these units, we will be more than happy to help you and create a unique shape that will be the perfect fit for your project. 

The rubber blanking grommets range in size, and in most vehicles, the right size of these units is between half an inch to a full inch in diameter. Once again, the size can be modified and they can be produced in smaller or larger sizes. The most important thing that you need to know is that they need to be a perfect fit for the opening if you don’t want to risk dust, dirt, and moisture from penetrating in your equipment or vehicle. They are used to let wires and cables pass through them freely, without risking the cords getting damaged or broken from the pressure, or from the sharp edges of the opening. 

When installing the rubber blanking grommets, you need to make sure that the surface is clean of any dirt or fluids, and you can do this just by cleaning it with a cloth. The reason why you need to prepare the surface is that if there is any debris under the grommet, it may not fit perfectly, and the moisture may cause rusting in your equipment.
