Conduit means to apply an extra layer of plastic or metal over the protective device to ensure complete safety. Conduit grommets will help you to pass more cables and wires with better support. Due to the conduit at the end of the grommet, there will be a second line of defence. It is crucial for sensitive wiring like in computers controlling ICU or such machines. Before choosing a conduit material for your conduit grommets, there are a few things you need to check. First, determine the place you will install these grommets. Flexibility and rigidity of the material play an essential role in the function and Durability of grommets. Here is a small requirement and characteristic chart of conduit materials. 

Plastic is the first choice for developing a flexible conduit grommet. These bend easily and remain viable for a longer time. Wiring inside the walls, robotic arm’s insulation is the primary sector of use of these grommets. Metals are also a good source of flexible conduit. Metal has good strength and the potential to resist crushing. So, metal conduits are the best for outside usage where there are chances of physical damage.
