General
Colour	Yellow/Green

The Helavia A2x25-C JV rubber grommets from Ses-Sterling are specifically designed for use in electrical and installation technology. These cable glands serve for the secure and tight fastening of cables and lines in electrical installations. The grommets are available in the colour Yellow/Green, which visually distinguishes them clearly from other cable types and thus enables easy identification during installation. The designation A2x25-C JV refers to the specific design of the grommets, which is intended for certain cable diameters and application areas.

Rubber grommets are elastic cable glands made of rubber, which, due to their shape and material properties, enable a secure, tight and at the same time flexible connection between cable and enclosure or control panel. They are frequently used in industrial electrical installations, building automation, as well as in the cabling of machines and plants. The colour Yellow/Green is commonly used in electrical engineering as a marking for protective conductors (PE conductors), making these grommets particularly suitable for use with protective conductors.

Functions and equipment in detail

The Helavia A2x25-C JV grommets are made of a flexible, durable rubber that offers high elasticity and shape stability. This ensures secure cable fastening without damaging the cable. The grommets are dimensioned to ensure a secure fit in the drill hole or cable entry. The use of rubber ensures good sealing, protecting against ingress of dust, moisture or other environmental influences. The grommets are designed for use in environments with temperatures from -30 °C to 90 °C, making them suitable for a wide range of indoor and outdoor applications.

Technology explained simply

The grommets operate on the principle of a cable clamp: when inserting the cable, the rubber is elastically deformed and adapts to the cable diameter. This creates a tight, mechanical hold that secures the cable against tensile and torsional forces. The elastic nature of the material allows adaptation to slight variations in cable diameter without impairing the sealing effect. The Yellow/Green colour supports visual differentiation in the installation network, especially when installing protective conductors, which require specific marking according to VDE and DIN standards.

Compatibility and accessories

The Helavia A2x25-C JV grommets are designed for use in standard installations, particularly in control panels, distributors and machine enclosures. They are compatible with drill holes and cable entries designed for cable diameters of approximately 25 mm. The grommets can be used with various cable types, provided their diameter is within the permissible tolerances.

Installation and mounting

Mounting is done by simply inserting the cable into the grommet sleeve and then inserting the grommet sleeve into the designated drill hole or cable entry. The elastic shape of the rubber ensures that the grommet sleeve automatically adapts to the cable diameter and creates a tight connection. No additional tool support is required. The grommets are designed for easy, quick and secure installation, making them efficient for daily use by electricians.

Advantages in operation

The use of Helavia A2x25-C JV rubber grommets provides a reliable, tight and mechanically stable connection between cable and enclosure. Material strength and temperature resistance ensure long service life and secure function even under difficult environmental conditions. The Yellow/Green colouring supports compliance with safety regulations and facilitates maintenance and inspection of the installation. The grommets are available in a pack of 100 pieces, making them economically attractive for series installations and larger projects.
