The sealing performance of Nylon Cable Gland is a very important step in judging the product quality. There are certain evaluation standards for the waterproof performance of waterproof joints in China, mainly looking at the two numbers after IP.

How to judge the sealing performance of waterproof connectors

Generally speaking, there are two numbers after the IP of waterproof connectors. The first number ranges from 0 to 6. The larger the number, the better the waterproof performance.
