There are many different types of rubber grommets and one of the ways they are classified is by size. The 7/8 id rubber grommet is most commonly used to seal holes on different devices and machines, protect and close pipes and other equipment, and protect cables and wires from snapping or getting damaged from any sharp edges or objects. These units can be used both inside and outdoors, and they can be exposed to different weather conditions without getting damaged. 

One thing that you should know about the 7/8 id rubber grommet is that the units come with different groove diameters, groove width, and a specific outside diameter. Because of this, you need to understand the exact type of product that you are getting, and just because the inside diameter fits your tasks, it does not mean that you should not check the other specifications. There are different ways to install the 7/8 id rubber grommet, and the most common ones include push and press in models. You can also wrap them around the cables or cords that you want to protect and you can also slit one side of the rubber unit to ensure that it will be properly secured around the wire without damaging it during the installation process. 

Choosing the right size of the unit is crucial, and as manufacturers, we can help you choose if you need the 7/8 id rubber grommet or if you need another size product for your specific task. You have to take every measurement properly, and if you have any questions on how that is done, you can always reach out to us. You should also pay attention to the shape of the unit because even though they most commonly come in a round shape, you can also customize them and request any other design that would be beneficial for you.
