When we need to install wires and cords in our equipment, that means that the wires need to be connected on the inside of the device, and they need to pass through different obstacles and protection layers to get to another panel or to be connected to an outlet outside. This means that there needs to be an opening that will let the cords freely pass through the closure. When we create those openings, we are aware that now we are letting the outside environment come into contact with our equipment. We all know that dust and moisture are the biggest enemies of electrical equipment, so we have to do something to seal the hole, and still let the cables pass freely. This is where the watertight grommet comes in. These small units are used to seal an opening, protect both the equipment and the wires that need to pass through, and at the same time, provide the needed space so that the cord can be connected to other outside panels.
A suitable rubber grommet can help reduce water ingress when its profile matches the cable and panel and it is installed correctly. The material alone does not make the entry watertight. Confirm the cable dimensions, panel cutout and thickness, contact surfaces and installation method, then verify the complete assembly against the required exposure and test conditions. Review heat, outdoor exposure and chemical compatibility for the selected compound. Contact us to confirm sample arrangements for fit and assembly evaluation; free samples may be available for eligible projects.
