General
Colour	Black

The Helavia A4x30-C rubber grommets from Ses-Sterling are black-coloured, flexible cable protection components specifically developed for use in electrical and IT installations. They serve as cable glands for secure and tight fixation of cables in pass-throughs, e.g. in enclosures, switch boxes or machines. The grommets are made of an elastic rubber material that ensures a tight seal and at the same time allows easy installation. With a length of 30 mm and an inner diameter of 4 mm, they are suitable for small to medium cable cross-sections, particularly in applications where mechanical and electrical insulation is required.

Applications
The Helavia A4x30-C rubber grommets are used in industrial electrical installations, automation technology, and IT infrastructure. They are used to protect cables when entering or exiting through enclosure walls or covers, to absorb mechanical stress and to ensure a tight connection. The grommets are particularly suitable for applications where sealing against dust, moisture or light contamination is required. Due to their black colour, they blend in visually with many technical environments, especially in black-painted or metallic enclosures.

Functions and Equipment in Detail
The grommets are designed as rubber grommets, meaning they are made of an elastic, rubber-like material that deforms when pressed into a hole or passage, creating a tight fit. The shape is cylindrical with a conical transition, which facilitates easy installation. The black colour is standard and corresponds to the product designation. The grommets do not require additional tools or adhesives for installation; they are simply pressed into the designated hole, where the elastic material adapts to the shape of the hole.

Technology Explained Simply
The functionality is based on the elastic deformation of the rubber material. When pressed into a hole, the grommet compresses and generates pressure that ensures a tight seal. The elastic recovery force ensures that the grommet maintains its position even with slight movements or vibrations. The material composition allows an operating temperature range of -30 °C to +90 °C, enabling use in a wide range of environments, including light industrial or outdoor installations. The grommets are not designed for extreme mechanical loads or aggressive chemicals, but for use in clean, dry or slightly moist environments.

Compatibility and Accessories
The Helavia A4x30-C grommets are designed for holes with a diameter of approximately 4 mm. They fit into standard pass-throughs found in switch boxes, control devices or machine enclosures. The grommets are not connected to any special accessories; they are used as individual components. The packaging unit contains 100 pieces, suitable for larger installations or series assembly. There are no specific compatibility specifications for particular manufacturers or products, as the grommets are universally applicable.

Installation and Mounting
Installation is tool-free. The grommet is simply pressed into the designated hole, where the elastic shape adapts to the hole. Installation does not require additional materials such as adhesives or sealing compounds. The grommets are designed to be easily pushed into the hole, creating a secure, tight fit. Installation is typically done from the inside of the enclosure, with the grommet protruding outward to protect the cable.

Advantages in Operation
The Helavia A4x30-C rubber grommets provide a reliable, tight seal that protects against dust, moisture and mechanical stress. The elastic material structure ensures a long service life and a stable connection, even with slight vibrations. The grommets are easy to install and require no additional tools or materials. The black colour allows for discreet integration into technical environments. The packaging with 100 pieces is suitable for professional users requiring larger quantities.
