The DK-TPE 3/5/8-2 cable glands from Ses-Sterling are black-coloured, flexible protective components made of thermoplastic elastomer (TPE), specifically developed for use in electrical and installation technology. They are designed for the safe and tight guidance of cables, lines or other flexible components through holes in panels, enclosures or other parts. The glands are available in a pack of 100 pieces and are particularly suitable for applications requiring mechanical protection as well as sealing against dust and moisture.

Cable glands made of TPE offer high elasticity and shape stability, allowing them to be easily inserted into holes while exerting a firm but not excessive tension on the cable passing through. The TPE material composition ensures good chemical resistance against many industrial and environmental media, enabling the glands to be used even in demanding environments. The colour black is standard and corresponds to common requirements in electrical installation, where visual differentiation of cables or lines is often not necessary.

Applications include mounting in enclosures, distribution boxes, machine housings or other technical devices where cables or lines are routed through wall or ceiling openings. The glands protect the insulation of the lines from mechanical damage, such as abrasion, cutting or pressure, and simultaneously prevent dust, moisture or small particles from entering the interior of the device. The designation DK-TPE 3/5/8-2 refers to the specific design and compatible hole sizes, with the numerical values indicating suitability for holes with diameters of 3 mm, 5 mm and 8 mm.

Functions and equipment in detail include a continuous, cylindrical shape with a slightly conical entry, facilitating easy insertion into the hole. The glands are made from a single material, without additional reinforcements or metallic components. The elastic property of the TPE material ensures that the glands adapt to the shape of the hole and create a tight seal. The weight specification of 0.14 g per piece is technically relevant, indicating the low mass and lightweight construction, which does not impose additional load during installation.

Technology explained simply means that the glands are made of a thermoplastic elastomer combining the properties of plastics (shape stability, heat resistance) and elastomers (elasticity, sealing effect). The material is shaped during production and then cooled, fixing the final form. The glands are not self-lubricating but rely on elastic recovery force to ensure a tight fit. The black colour is not only aesthetic but also functional, as it is UV-resistant and thus does not degrade or discolour quickly in outdoor applications or environments with light exposure.

Compatibility and accessories refer to use with holes of 3 mm, 5 mm and 8 mm diameter. The glands are not designed for larger or smaller holes, as precise fit is essential for sealing performance. There are no specific accessories offered by Ses-Sterling for these glands; they are used directly during installation without additional tools. The glands are not intended for use in explosive environments or areas with extremely high temperatures, as this is not mentioned in the manufacturer's specifications.

Installation and mounting are performed by simply inserting the glands into the pre-drilled opening. The elastic shape ensures that the glands automatically adapt to the hole and create a secure connection. No additional tool support is required, as the glands remain in place due to their shape and material strength. Installation typically occurs before cable routing, with the glands positioned to allow safe passage for the cables.

Operational advantages include easy handling, high reliability and long service life. The glands prevent mechanical damage to cables and ensure a clean, orderly installation. The material quality ensures high resistance to mechanical stress and environmental influences, increasing maintenance-free operation and operational safety. The pack of 100 pieces enables cost-effective procurement for larger projects or series installations.
