General
Colour	Black

The Helavia DG 9 membrane grommets from Ses-Sterling are black-coloured protective components made of polychloroprene rubber, specifically developed for use in electrical and IT installations. They serve as rubber grommets for the safe and tight guidance of cables and lines through drill holes in components such as wall plates, enclosures or metal structures. The Helavia DG 9 black model is part of the HELAVIA product series and is supplied in a pack of 100 pieces. Each individual grommet weighs 2.49 g, with the total packaging weight amounting to 0.249 kg.

Applications
The Membrantüllen DG 9 are suitable for use in indoor and outdoor environments, particularly in areas where mechanical protection for cables and lines is required. They are frequently used in electrical installations, during the mounting of network components or in industrial electronics to protect cables from mechanical damage, such as abrasion or pressure. The application occurs at points where cables are routed through drill holes in components, ensuring a tight and flexible guidance.

Functions and Features in Detail
The grommets are made of polychloroprene rubber, an elastic and durable material offering high flexibility and mechanical strength. The black colouring is standard and corresponds to the product designation Helavia DG 9 black. The shape of the grommets is designed to elastically adapt to cable diameters, ensuring a tight but not overly tight fit. This prevents dust, moisture or other particles from entering the drill hole, thereby increasing the service life of the cables and the safety of the installation.

Technology Explained Simply
The Membrantüllen DG 9 function as cable clamps, enclosing the cable through their elastic structure and simultaneously forming a mechanical protective layer. The polychloroprene rubber material is characterised by high resistance to mechanical stress, temperature fluctuations and environmental influences. The grommets are designed to be easily inserted into the drill hole, ensuring a secure, tight fit. The elastic expansion allows adaptation to various cable diameters within a specific range, without damaging the cable.

Compatibility and Accessories
The Membrantüllen DG 9 are universally applicable and compatible with a wide range of cable types and installation systems. They fit into drill holes intended for cable routing and can be used in various components such as enclosures, wall plates or metal structures. The application requires no additional tools or aids – the grommets can be installed by simply inserting them into the drill hole.

Installation and Mounting
The installation of the Membrantüllen DG 9 is carried out by simply inserting them into the designated drill hole. The elastic structure of the material enables a secure and tight fit without requiring additional fastening means. The grommets are designed to be easily pushed into the drill hole, enclosing the cable. The installation requires no special tools or additional steps – the grommets are ready for immediate use and automatically adapt to the cable diameter.

Operational Advantages
The use of Membrantüllen DG 9 offers several operational advantages: they protect cables from mechanical damage, prevent the ingress of dust and moisture, and increase the safety of the installation. The elastic structure ensures a tight and flexible guidance that remains stable even under movement or vibration during operation. The grommets are easy to install and require no additional tools, reducing installation time. The use of polychloroprene rubber ensures a long service life and resistance to environmental influences.
