Product Advantages

Superior sealing performance prevents the intrusion of moisture, dust, and other external elements, protecting the electronic components inside from damage. This is especially important in outdoor or humid environments, where the intrusion of moisture and dust can lead to short circuits or other electrical failures.

In addition, this rubber part has good weather resistance and can resist the effects of extreme environmental conditions such as high temperature, low temperature and high humidity, keeping its physical and chemical properties stable, thus ensuring the long-term reliability of the aviation plug.
