The grommets are extremely versatile units, and the tube grommet is said to be one of the most commonly used ones. These units are different than the standard ones because they, as the name suggests, are shaped like a tube. They are most frequently used in specific installations, where the thickness of the material is larger. The tube grommet can be made of different materials, and rubber and silicone are the most common ones. Just like the standard units, they can be used to protect different types of equipment and gadgets, and they are most commonly used in the transportation industry, electronics, and they can also be used in aerospace. Note that they are mostly used to protect the device from vibrations, and to prevent the hole made from additional widening and damaging the device. They can also help with noise reduction, and they can be used for sealing in some cases. Depending on the unit at hand, they will protect both the equipment and the cable from getting damaged by dust and moisture, and they can prevent rusting and mold. 

In most cases, the tube grommet will protect your device from different harsh chemicals, and they are made to withstand high temperatures. Remember that depending on the model and material at hand, they can withstand temperatures as low as – 70 degrees Celsius, and as high as 300 degrees Celsius. If you are not sure which type of tube grommet is the right one for your project, you can easily contact the supplier or the manufacturer, and collaborate together to find the best material for the project, size, and model that will help you get the job done. The inside diameter of the tube grommet can vary between 2mm and 100mm, whereas the outside one can go between 5mm and 120mm. Note that you can find smaller or larger sizes, once again, depending on the job at hand.
