General
Colour	Yellow

The Helavia A3x25-FC rubber grommets from Ses-Sterling are specifically designed for use in electrical and installation technology. They serve as a cable gland for secure and tight fixation of cables in devices, enclosures or other electrical units. The grommets are available in the colour yellow and are made of an elastic material that ensures a firm connection between cable and housing. The designation A3x25-FC indicates the specific dimensions and functions, with the type designation defined in the manufacturer's catalogue as Helavia A3x25-FC yellow.

Applications
These rubber grommets are suitable for applications requiring mechanical and electrical insulation, as well as protection against dust and moisture. They are commonly used in industrial electrical installations, machine and plant engineering, and building automation. The grommets are designed for cables with a diameter of up to 25 mm and allow for secure cable routing through holes in housings or control panels. The yellow colour serves as a visual identifier and facilitates recognition during installation and maintenance.

Functions and Features in Detail
The Helavia A3x25-FC grommets are designed as cable clamps, meaning they hold the cable securely through an elastic constriction while simultaneously providing a tight seal. The material is flexible enough to enclose the cable without damage, while also offering high resistance to mechanical stress. The grommets are designed for temperature resistance from -30 to 90 °C, making them suitable for use in environments with varying climatic conditions. The packaging unit contains 100 pieces, which is advantageous for larger installations or series assembly.

Technical Explanation
The designation A3x25-FC describes the technical parameters of the grommets: A3 refers to the component group, 25 to the maximum cable diameter in millimetres, and FC stands for the function as a securing and sealing element. The material is rubber, offering high elasticity and resistance to wear. The yellow colour is not only visually distinct but can also serve as an identifier for specific application areas, e.g. in safety technology or for special cable types. The grommets are not intended for use in explosive atmospheres, as no corresponding approvals or standards are mentioned.

Compatibility and Accessories
The Helavia A3x25-FC grommets are compatible with standard cables with a diameter up to 25 mm and can be installed in holes of corresponding diameter. They are suitable for use in electrical enclosures, control devices and other housings requiring cable entry. No specific accessories are mentioned in the manufacturer's catalogue; the grommets are supplied as individual components. Installation requires no additional tools — mounting is done by simply inserting the cable and then securing the grommet in the housing.

Installation and Mounting
Mounting of the rubber grommets is done by inserting the cable into the grommet and then placing it into the hole in the housing. The elastic structure of the grommet ensures that the cable is held securely and a tight seal is created. It is important that the hole in the housing has the specified diameter to ensure proper fit.

Operational Advantages
The Helavia A3x25-FC grommets provide a reliable and durable cable fixation that protects against mechanical damage and environmental influences. The simple installation and minimal space requirement make them a practical solution for various installation scenarios. The temperature resistance from -30 to 90 °C allows use in a wide range of environments, from indoor to outdoor applications. The yellow colour facilitates visual inspection and identification during operation, making maintenance and inspection more efficient. The grommets are available in a pack of 100 pieces, making them economically attractive for series applications.

The grommets are not supplied with additional components such as instructions, tools or packaging materials not mentioned in the manufacturer's catalogue. The packaging contains exclusively 100 pieces of yellow rubber grommets. The weight specifications per piece (0.525 g) and for the entire package (0.053 kg) are for logistics purposes and are not part of the technical function.
