General
Colour	Black

The Helavia DA 160/220/30 black is a cable gland made of polychloroprene rubber, designed for use in the electrical and installation industry. It provides secure and tight cable and wiring passage through wall or ceiling openings, particularly in areas where mechanical and chemical resistance as well as high flexibility are required. The gland is black and supplied in a pack of 100 pieces.

Applications
This cable gland is suitable for use in industrial and commercial installations where cables must pass through structural elements such as walls, ceilings, or machine housings. It protects the wiring from mechanical stress, such as friction or pressure, and simultaneously prevents the ingress of dust, moisture, or small particles. Due to its composition of polychloroprene rubber, it is resistant to many chemical influences, making it suitable for applications in environments with aggressive media.

Functions and Features in Detail
The gland enables secure and tight cable passage with a maximum diameter of 30 mm. The designation DA 160/220/30 refers to the external dimensions of the gland: an outer diameter of 160 mm, a total length of 220 mm, and a maximum cable passage of 30 mm. The shape is cylindrical with a conical transition, allowing easy installation and a secure fit in drill holes or openings. The surface is smooth, facilitating cable insertion and minimizing friction.

Technology Explained Simply
The gland is made of polychloroprene rubber, an elastic plastic known for its high flexibility, weather resistance, and chemical resistance. These properties make the material particularly suitable for use in electrical installations, where it often comes into contact with moisture, oil, solvents, or other chemical substances. The black color is not only aesthetic but also functional, as it is UV-resistant and thus maintains its properties over time even in outdoor applications or sunlit rooms.

Compatibility and Accessories
The Helavia DA 160/220/30 black is designed for use with cables and wiring having a maximum diameter of 30 mm. It fits into drill holes or openings with a diameter of approximately 160 mm. The gland is supplied in a pack of 100 pieces, making it suitable for larger installations or series mounting.

Installation and Mounting
Mounting is done by simply inserting the gland into the designated opening, where the conical shape ensures a secure fit. Cables are passed through the central hole, and the elastic properties of the material create a tight seal. The gland can be installed without tools, although depending on the component and environment, preparation of the hole may be required.

Operational Advantages
The gland provides reliable sealing against dust and moisture, increasing the service life of the cables and improving installation safety. Its high mechanical strength protects the wiring from damage due to external influences. The material's resistance to chemical influences makes the gland suitable even for demanding environments. The simple installation and high availability in packs of 100 pieces facilitate planning and execution of installations.
