The Helavia A3x25-FM rubber grommets from Ses-Sterling are specifically designed for use in electrical and IT installations. They serve as a cable gland for secure and tight fixation of cables in openings, particularly in switch cabinets, distribution boxes, or other electrical enclosures. The product is available in the color White and is supplied in a pack of 1000 pieces. The grommets are made of an elastic material that ensures reliable sealing and allows for easy installation.

Applications
These rubber grommets are suitable for use in industrial electrical installations as well as in building and communication technology. They are frequently used in switchgear, distribution boxes, or for cabling in control and automation systems. The grommets are designed for cables with a diameter of up to 25 mm and enable secure cable routing through holes or openings in the enclosure. The white color ensures good visibility and blends aesthetically into many technical environments.

Functions and Features in Detail
The Helavia A3x25-FM features a crimping nipple structure that is pulled through the cable during installation. The cable is securely held by the elastic shape of the grommet, achieving both mechanical stabilization and simultaneous sealing. The grommet adapts to the cable diameter, preventing slippage or loosening. The material properties ensure high flexibility and durability under normal operating conditions.

Technical Explanation
The grommet is made from a special rubber compound that offers good elasticity and resistance to mechanical stress. The conical shape guides the cable automatically into the securing zone during insertion. Sealing is achieved through the elastic pressure of the grommet on the cable, preventing air and moisture ingress. The grommet is not intended for use in explosive environments or at high temperatures, as no specific approvals for these applications are stated.

Compatibility and Accessories
The Helavia A3x25-FM is compatible with standard holes in metal or plastic enclosures with a diameter of at least 25 mm. It can be used in combination with other protection and securing elements such as cable lugs, screw terminals, or switch cabinets. The grommet does not require additional tools or accessories; installation is done manually by pulling the cable through. No specific accessory items are mentioned in the manufacturer’s offering.

Installation and Mounting
Installation is done by simply pulling the cable through the grommet and then inserting it through the hole in the enclosure. The elastic shape of the grommet ensures the cable is securely held after installation. No additional fastening or tools are required. The grommet should be positioned so that it fully engages in the hole and provides even pressure distribution on the cable. Installation is quick and does not require special expertise.

Operational Advantages
The Helavia A3x25-FM provides reliable mechanical fixation and sealing of cables in electrical enclosures. The simple installation and minimal space requirement make it a practical component in daily installations. The grommet is suitable for indoor use and offers protection against dust and moisture. The pack of 1000 pieces enables economical use in larger projects. The white color supports visual inspection and integration into existing installations.
