Cable Glands & Stopping Plugs

In cleanrooms or industrial environments small contaminations or sealed equipment can harm safety or reduce how well machines work. Cable glands and stopping plugs make airtight and watertight seals. They stop dust, vapors, or unwanted particles from entering through cable entry points. This has great importance in industries like food processing, electronics manufacturing, oil and gas, or pharmaceuticals. These sectors need to meet strict cleanliness or explosion-proof standards.

Selecting the appropriate type depends on several factors. You should think about the cable size where you'll use it (such as indoors outdoors, or in areas with explosion risks), the material's suitability (like nylon stainless steel, or brass), and the needed IP rating to keep out water or dust. For use in dangerous areas, you need to pick flameproof or explosion-proof glands and plugs that meet standards such as ATEX or IECEx. For cleanroom applications, the parts should help reduce particles and withstand cleaning chemicals.

You can remove stopping plugs by either pulling them out or unscrewing them when you need extra cable openings. Whether you can reuse them usually depends on the material. Metal plugs are often reusable, but plastic ones may lose their fit or wear down after removal. Always inspect the plug before reusing it to make sure it still seals .

These components are installed in control panels, junction boxes, enclosures, and industrial equipment. People use them both inside and outside to ensure electrical safety and protect systems. In cleanrooms, they prevent cables from contaminating the environment helping to preserve the ISO classification. In hazardous zones, they stop ignition sources from triggering explosions.

A cable gland secures and seals a cable's endpoint to equipment or an enclosure. It provides strain relief and protection from conditions like dust or moisture. Cable termination however, focuses on preparing and connecting the cable's end to a terminal or connector to make an electrical link. The gland ensures the cable stays secure and shielded, while termination handles the proper electrical connection.
