Ses-Sterling 02010008010 Helavia A8x50-C black rubber grommet -30 to 90°C content_copy

The Helavia A8x50-C rubber grommets from Ses-Sterling are black-coloured cable protection components specifically developed for use in installations where cables or lines are passed through drill holes in enclosures, wall linings or other components. These grommets provide mechanical and electrical protection by creating a tight, flexible seal between the cable and the penetration element. The designation A8x50-C describes the technical dimensions: an inner diameter of 8 mm and a total length of 50 mm, with the "C" indicating the black colour. The grommets are made from an elastic rubber material that offers high flexibility and shape stability, enabling secure fixation of cables of various diameters while simultaneously cushioning mechanical stresses such as tension or vibration.

Applications
Rubber grommets of type Helavia A8x50-C are used in a wide range of installation scenarios, particularly in electrical and IT technology. They are employed to safely route cables through drill holes in machines, devices, enclosures or in building installations. The grommets protect the cable sheathing from mechanical damage, such as cracks or abrasion, and prevent dust, moisture or small particles from entering the device. Due to their temperature resistance from -30 to 90 °C, they are also suitable for environments with varying climatic conditions, for example in outdoor installations, industrial environments or in vehicles.

Functions and Equipment in Detail
The grommets feature a conical, bulge-shaped cross-section that elastically deforms when inserted into a drill hole, ensuring a secure fit. The inner diameter of 8 mm allows the passage of cables with an outer diameter of up to approximately 8 mm, with the elastic expansion of the material providing a certain tolerance for minor deviations. The length of 50 mm ensures that the grommets penetrate sufficiently deep into the drill hole and enable stable anchoring. The black colour is not only visually uniform but also functional, as it is UV-resistant and thus does not discolour or degrade when exposed to prolonged outdoor lighting.

Technology Explained Simply
The operation of the rubber grommets is based on the elastic deformation of the material. When inserted into a drill hole, the bulge of the grommet is compressed, creating a tight fit. Once the cable is passed through the grommet, the bulge is again elastically deformed and encloses the cable, providing mechanical fixation and simultaneous sealing. The material composition ensures high elasticity and resistance to mechanical stress without the grommet losing its shape after repeated use. The temperature resistance from -30 to 90 °C makes them suitable for applications in environments with variable climatic conditions, without the material becoming brittle or losing its elasticity.

The grommets are available in a pack of 100 pieces, making them particularly cost-effective for series installations or larger projects. The weight per piece is 3.9 g, indicating a lightweight yet robust material. The packaging weight is 0.39 kg, corresponding to the total mass of 100 individual pieces.

Compatibility and Accessories
The Helavia A8x50-C grommets are universally applicable and compatible with drill holes of 8 mm diameter. They can be used in combination with various cable types, such as data cables, control lines or power cables, as long as the outer cable diameter falls within the elastic tolerance of the grommet. The grommets are not specifically designed for a particular standard or certification, but meet general requirements for cable protection in electrical and IT installations. There are no specific accessories that are directly combined with this item, as the grommets function as individual components.

Installation and Mounting
Mounting is done by simply inserting the grommet into the designated drill hole. The elastic shape of the bulge ensures that the grommet automatically adapts to the hole and provides a secure fit. Subsequently, the cable is passed through the grommet, causing the bulge to deform again and hold the cable firmly. The installation requires no tools or additional materials. The grommets are designed for single use and cannot be reused, as the elastic shape cannot be fully restored after the first use.

Operational Advantages
The Helavia A8x50-C grommets offer reliable, long-lasting sealing and mechanical protection for cables. Their simple installation and universal usability make them a practical solution for installations in various industries. The temperature resistance and UV resistance increase service life and reliability in demanding environments. The pack of 100 pieces enables efficient handling in larger projects, reducing working time and lowering the cost per unit.
