Product Description

The WK SP threaded coupling connector typically consists of a male plug and a female socket. The male plug has a threaded coupling nut, while the female socket has a corresponding threaded receptacle. The threads on the coupling nut and receptacle enable a secure and tight connection when twisted together.


To ensure waterproofing, SP threaded coupling connectors often incorporate additional sealing features. These may include rubber gaskets, O-rings, or other sealing elements placed between the mating surfaces of the plug and socket. These seals prevent water, moisture, and dirt from entering the connection points.


SP threaded coupling waterproof connectors are available in various sizes, configurations, and voltage/current ratings to suit different applications. They are commonly used in outdoor lighting, power distribution systems, telecommunications equipment, and other industrial or commercial applications where protection against the elements is essential.


When using SP threaded coupling waterproof connectors, it's important to ensure proper mating and alignment of the threads to achieve a secure and watertight connection. Following the manufacturer's instructions and guidelines for installation and maintenance will help ensure the reliable and waterproof performance of these connectors.
