Is My Wiring Harness Waterproof?

When dealing with electrical wiring, the last thing you want to worry about is whether the wires are adequately protected against weather, water, and other elements that could impact performance. A wiring harness, also commonly referred to as a wire harness, covers electronic wires with a thin exterior sheath to help ensure that it is adequately protected from the elements.

But does having a wiring harness over your electronic wires ensure that it is waterproof? After all, while the purpose of a wiring harness is to keep wires protected, that doesn’t necessarily guarantee that there will be no damage to them if they are exposed to water. Here, we’ll discuss the reasons why you may want to consider a waterproof wiring harness, along with the best way to ensure that your wiring harness is well-protected against water exposure.

Do I Need a Waterproof Wiring Harness?

The answer to this question comes down to one thing: whether your electronic wiring bundle is at risk of being anywhere near water. A wiring harness located in an outdoor enclosure, for example, is at greater risk of being exposed to the elements than a wiring harness in an indoor electrical appliance. If there is any possibility that the wiring harness will come in contact with water, it’s a good idea to waterproof it.

How Do You Waterproof a Wiring Harness?

Ordering a custom-made wiring harness gives you the freedom to choose from a multitude of options to best fit your needs. Along with dictating the desired length of your custom wiring harness, you can also choose from a variety of cable shield types, raw materials, colors, labels, and connector housings to create a one-of-a-kind wiring harness for your project. In order to ensure that your custom wiring harness is waterproof, you may choose a connector housing equipped with gaskets and seals made for the purpose of keeping water out. Customizing your wiring harness is your best bet for ensuring that it is truly waterproof.
