As you know, the primary use and application of panel grommets is to ensure that whatever it is that is passing through the hole in the panel is insulated and protected. In general, panel grommets are used mostly with metal panels, as they’re the ones with the sharpest edges and they pose the biggest threat to the cabling and wiring that goes through them. That is why we use a wide variety of panel grommets.

Not only do they offer insulation and protection, but they also deal with the vibrations rather well, which is very important if you’re running wiring through a thin, metal panel that is highly susceptible to transferring vibrations. For instance, many high-speed optic fibre internet cables cannot sustain any major vibrations, as the vibrations affect the cables ability to perform. Additionally, most of those cables can be easily damaged, so an added level of protection is always welcome.

Panel grommets are also quite often used in the automotive industry, where you have to run a lot of cables and wires through several panels, especially nowadays with modern vehicles being highly dependent on various electronics. Another reason why these are so widely used is the fact that they can be highly customizable. They can be different in size, thickness, material, type, colour and so on. 

Most manufacturers will be able to give you a piece of sound advice on which exact type of panel grommet you need, based on your requirements that you’ve provided them with. Additionally, panel grommets are very affordable, especially if purchased in bulk. Large companies, such as automobile manufacturers, often purchase grommets in bulk, as that’s the best way for them to get a good deal.
