Use Of Seals On Automotive Wiring Harnesses

The durability and reliability of automotive parts are increasingly valued. As a protective material, rubber parts are widely used in automobiles. The importance of the Silicone Weather Pack Seals is self-evident, especially for harness protection of the engine compartment and the lower chassis of the car. Because usually the two places are in a harsh environment with a high probability. There is a concept of "wet zone" to know. In general, we expose the engine compartment and the lower part of the car to the air. The area often affected by rain and water is called "wet zone", correspondingly, the cockpit and baggage. Boxes and other parts are basically not affected by rain. This part is called "dry area".

One of the biggest functions of the wire harness seal is to isolate the wet zone and the dry zone. This is an application. The common part is to install one between the engine compartment and the cockpit to separate the dry zone from the wet zone. The rear wheel ABS harness needs to be equipped with a sealing ring, specifically under the rear seat (such as golf). There is a sealing ring separating the inner and outer parts to ensure that the water at the bottom does not leak into the cab during driving;

Each qualified wire harness is subjected to a hermetic seal to ensure that the seal on the wire harness can function. Generally, in the wire harness factory, we use vacuum test equipment to work.
