General
Colour	Light blue

The Helavia A3x25-FC rubber grommets from Ses-Sterling are specifically designed for use in electrical and installation technology. They serve as protection for cables and wires, particularly when securing them in cable entry plates, socket outlets, switches, or other electrical components. The grommets are available in the colour light blue and provide a secure, long-lasting seal to prevent mechanical damage and environmental influences such as dust or moisture. The designation A3x25-FC refers to the specific design of the grommet, with the marking “FC” indicating a version with a guiding flange that enables precise fitting into the designated holes.

Applications
These rubber grommets are suitable for use in indoor environments as well as in protected outdoor areas where a tight and flexible cable routing is required. They are commonly used in building installations, industrial electrical engineering, and during the mounting of socket outlets and switches. The grommets protect cables from mechanical wear, such as abrasion or pressure, and prevent foreign objects from entering electrical components. The colour light blue serves as a visual identifier and can be used for structural or functional differentiation within an installation.

Functions and Features in Detail
The Helavia A3x25-FC grommets are made from an elastic rubber material that offers high flexibility and shape stability. The grommet is slid over the cable and inserted into the designated hole, where the guiding flange (FC) ensures secure and centred positioning. The elastic properties of the material allow for a tight seal without damaging the cable. The grommets are suitable for a wide range of cable diameters, with precise fit ensured through shape design and material selection. The use of rubber ensures high abrasion resistance and long service life under normal operating conditions.

Technology Explained Simply
The grommet is slid over the cable and inserted into a hole in the component (e.g. socket outlet, switch, housing). The elastic shape of the rubber ensures that the grommet adapts to the cable diameter and creates a tight, pressure-resistant connection. The guiding flange (FC) prevents shifting or twisting of the grommet in the hole and ensures secure installation. The rubber composition allows for an operating temperature range of -30 °C to +90 °C, enabling use in a variety of environments, including light industrial applications. The grommets are not intended for use in explosive environments or under extreme mechanical stress.

Compatibility and Accessories
The Helavia A3x25-FC grommets are compatible with standard holes in electrical components, particularly in socket outlets, switches, and cable entry plates. They can be used with various cable types, provided the cable diameter falls within the permissible tolerances. The grommets are not specifically designed for particular brands or models, but conform to general standards in electrical installation. There are no specific accessories required for using these grommets. Installation is tool-free and requires no additional materials.

Installation and Mounting
Installation is performed by simply sliding the grommet over the cable and inserting it into the hole in the component. The guiding flange ensures correct positioning. It is important to avoid excessive compression or deformation of the cable to prevent damage. The grommets are designed for single-use installation and should not be reused. The packaging contains 100 pieces, which is sufficient for larger installations.

Operational Advantages
The Helavia A3x25-FC grommets provide a reliable and durable seal that extends the service life of the electrical installation. The elastic material ensures a secure fit without damaging the cable. The colour light blue allows for easy visual identification within an installation. The grommets are easy to install, require no tools, and are suitable for use in various applications. The temperature resistance from -30 °C to +90 °C expands the range of possible environments for use.
