Rubber grommets, rubber bellows or however else you want to call them, are small rubber components used to cables, wires or pipes passing through a sharp opening. Another name for this type of rubber grommet is open rubber grommet. 

As you can tell by the name, the open rubber grommet sports a large opening in the middle for the cables, wires or pipes to run through. We have open rubber grommets available in a plethora of sizes so they can fit your every need. The way you will choose your perfect grommet is by choosing the correct size first. The size measurements you will want to pay most attention to are the inner and outer diameter. The inner diameter will be correspondent to the size of the opening inside of the open rubber grommet. You will choose that based on what you need to run through the grommet and how much clearance you need for it. The outer diameter will match the size of the opening that you are trying to insulate with the grommet. Additionally, you will want to pay special attention to the open rubber grommet groove width in order to make sure your grommet fits nice and snug in the panel you’re inserting it in.

Apart from size, the open rubber grommet can differ in colour, type, or material from which it is made of. As for colour, the only difference is of cosmetic nature, while type and material affect the performance of the grommet. For instance, a natural rubber open rubber grommet will not behave the same as the one made from silicone or nitrile. Some differences might be minute, some slightly more noticeable, so you will have to choose carefully based on the application you need the grommet for. Overall, most materials will be suitable for common use-case scenarios, but if you need it for something particular, we are more than willing to assist you.
