Waterproof nylon cable connectors are designed to withstand exposure to water and moisture to a certain extent, but they are not typically intended to be submerged in water for prolonged periods. While these connectors provide a level of protection against water ingress, they may not be completely watertight and may not be suitable for immersion in water.
The level of waterproofing and the specific environmental rating of nylon cable connectors can vary depending on the manufacturer and the intended application. Some connectors may be rated for outdoor use and provide protection against rain, splashes, and temporary exposure to water, but they may not be suitable for continuous submersion in water.
It's essential to consult the manufacturer's specifications and installation guidelines for the specific nylon cable connectors you are using to determine their suitability for your intended application. If submersion in water is required, it may be necessary to use specialized waterproof connectors that are specifically designed and rated for underwater use to ensure reliable performance and protection against water ingress.
