General
Colour	Black

The Helavia A1Kx25-C rubber grommets from Ses-Sterling are black-coloured, flexible protective sleeve elements for use in electrical and installation technology. They serve as cable protection and cable entry element when routing cables through drilled holes in panels, enclosures or other components. The grommets are specifically designed for use in installations where secure and durable cable guidance is required without damaging the cable insulation. The designation A1Kx25-C refers to the technical configuration and colour, with the colour black explicitly mentioned in the product description.

Applications
These rubber grommets are suitable for use in industrial electrical installations, building automation, and machine and equipment cabling. They are often used in combination with cable glands or other cable entry elements to guide cables securely and seal them. The grommets are designed for temperature loads of -30 to 90°C, making them suitable for applications in indoor and outdoor environments, provided ambient conditions remain within this temperature range. Use in damp or dusty environments is possible, provided no additional protection requirements such as IP ratings are necessary.

Functions and Equipment in Detail
The grommets are made of an elastic rubber material that offers high flexibility and shape stability. They enable secure cable guidance without mechanically stressing the cable insulation. The inner surface is smooth to minimise friction and wear when pulling cables through. The outer shape is cylindrical, allowing for easy installation into drilled holes. The grommets are not self-cutting and must be inserted into pre-drilled openings. The packaging unit contains 100 pcs, suitable for larger installations or series assembly.

Technology Explained Simply
The designation A1Kx25-C describes the technical configuration of the grommets. The marking A1K" refers to the product series and geometric properties, while "x25 indicates the hole size intended for use. The colour black is not only visually uniform but can also aid in distinguishing these grommets from other cable protection systems in specific applications, such as industrial electrical installations. The grommets are made of an elastic material that can be easily deformed during installation to securely enclose the cable. Material strength ensures that the grommets retain their function even after repeated insertion and removal of cables.

Compatibility and Accessories
The Helavia A1Kx25-C rubber grommets are suitable for use in combination with cable glands, cable entry elements, and other installation systems. They fit into holes with a diameter corresponding to the x25 marking. Use with other products from the Helavia series is possible, provided geometric dimensions match. No specific accessories are mentioned in the manufacturer's text, so compatibility is limited to standard installation systems.

Installation and Mounting
Installation is performed by inserting the grommet into a pre-drilled hole. The hole should have the specified diameter to ensure a secure fit. The grommet is manually pressed into the hole, with the elastic material enabling a tight seal around the cable. After insertion, the cable is pulled through the grommet. Installation requires no tools, as the grommets can be installed without additional aids due to their elasticity.

The grommets are designed for use in installations where secure and durable cable guidance is required without damaging the insulation. Use in damp or dusty environments is possible, provided no additional protection requirements such as IP ratings are necessary.

Operational Advantages
The grommets provide reliable cable protection and prevent dust, moisture, or small particles from entering the hole. The elastic structure ensures a tight fit that remains intact even under slight vibrations or movements during operation. The colour black allows for visual harmonisation with other installation components. The packaging unit of 100 pcs is suitable for larger projects and reduces installation time through pre-quantified amounts. The grommets are designed for use within a temperature range of -30 to 90°C, enabling broad applicability in various environments.
