Protecting your cords and wires from damage is crucial, and sometimes you need an extra layer of safety so you know that water and dirt cannot penetrate inside them. When we make a hole inside a device, our walls, or pretty much anywhere, and we need to put a cable through it, we have to make sure that both the hole and the cord are not going to get damaged. The waterproof cable grommet is the best way to make sure that your device, along with the wire are going to stay intact for a long time. 

The waterproof cable grommet is mostly used in industries including electronics and the automotive one, and the reason for this is that this accessory can withstand extreme temperatures, it will not get damaged under pressure, and it has excellent tensile strength. Some of the other physical properties that these accessories have include great elongation at the break, excellent abrasion resistance, and they will not tear with use. 

The waterproof cable grommet can be installed inside any device of your choosing, and it can also be put inside your walls. The way they work is they are wrapped around the cord, and they seal the hole that the cable passes through. Since they are waterproof, they will not get damaged even when they are used outdoors, and they will not let any dust penetrate inside the hole. With this, they prevent mold and rust, and they increase the lifetime of your devices and appliances. Note that the waterproof cable grommet shields both the wires and the holes, and they are especially preferred in the automotive industry. The only thing you need to pay extra attention to is the size of the unit, as it should never be too small so there is space between it and the edges of the hole, and it should not be too tight so it applies pressure on the cable.
