The Helavia A4x30-FM rubber grommets from Ses-Sterling are specifically designed for use in electrical and installation technology. These rubber grommets serve as cable glands and enable a secure, tight, and flexible fixation of cables in cable entries, e.g. in control enclosures, housings or other electrical installations. The grommets are available in the colour yellow and feature a robust design suitable for use in industrial and commercial environments. The designation A4x30-FM indicates the dimensions: an inner diameter of 4 mm and a length of 30 mm, where the FM refers to the specific shape and function of the grommet.

Applications
These rubber grommets are used in electrical installation, machine building, automation technology, and building and plant automation. They are used to route cables through housing walls, providing mechanical protection while simultaneously ensuring a tight seal. The grommets are particularly suitable for small to medium cable diameters and support proper cabling in enclosed control systems. The yellow colour serves as a visual identifier and can be used for quick identification during maintenance or installation work.

Functions and equipment in detail
The Helavia A4x30-FM is a cable gland made of elastic material, characterised by high elasticity and shape stability. During installation, the cable is passed through the grommet, which is then inserted into the designated hole or cable entry. The elastic pressure securely holds the cable in place, while simultaneously achieving a tight seal against dust, moisture and small particles. The grommets are designed for use at temperatures from -30 °C to +90 °C, making them suitable for a wide range of indoor and outdoor applications. The yellow colour is clearly visible and supports visual differentiation in the installation environment.

Technology explained simply
The rubber grommet is made of an elastic material that compresses when inserted into a hole or cable entry and then exerts elastic restoring force to securely hold the cable. This principle enables secure fixation without additional tools or screw connections. The grommet adapts to the cable diameter, achieving optimal sealing. The material composition ensures high resistance to mechanical stresses, such as tensile and bending forces, as well as environmental influences within the specified temperature range. The length of 30 mm provides sufficient clearance for installation in various housing constructions.

Compatibility and accessories
The Helavia A4x30-FM is designed for cables with a diameter of approximately 4 mm and fits into holes of corresponding diameter. The grommets are universally applicable and can be used in various control enclosures, control housings and other electrical devices. They are not specifically designed for a particular brand or product series, but are designed as a standard component for cable entries. Use in combination with other protection or mounting elements is possible, provided mechanical and thermal loads remain within the specified limits.

Installation and mounting
Installation is tool-free. The cable is passed through the grommet, and then the grommet is inserted into the designated hole or cable entry. The elastic pressure of the grommet securely fixes the cable. The grommets are designed for easy handling and can be used in series assembly or individual installations. The packaging contains 1000 pieces, making them suitable for large projects or retail orders.

Advantages in operation
The rubber grommets Helavia A4x30-FM provide a reliable and tight cable entry, ensuring the integrity of the installation. The high temperature resistance from -30 °C to +90 °C allows use in various environments, from climate-controlled rooms to industrial facilities. The yellow colour facilitates visual identification and can be helpful during maintenance work or for compliance with safety regulations. The tool-free installation reduces installation effort and increases efficiency during cabling. The grommets are designed for use in electrical systems that require secure and tight cable routing.
