The Helavia DA 20/65/20 black is a gland made of polychloroprene rubber, designed for use in electrical and installation technology. The manufacturer is Ses-Sterling, and the product is distributed under the manufacturer's number 02520003010. This gland provides secure and tight cable or wire guidance through enclosures, switch boxes, or other components, offering reliable protection against mechanical damage and environmental influences. The designation DA 20/65/20 describes the technical dimensions: an inner diameter of 20 mm, a total length of 65 mm, and an outer diameter of 20 mm. The product is black in colour, making it suitable for use in industrial and technical applications.

Gland seals are specially designed protective devices that shield cables during passage through a wall or enclosure from mechanical stresses such as friction, pressure, or bending. The Helavia DA 20/65/20 black is made of polychloroprene rubber, an elastic and durable material known for its high flexibility and chemical resistance. This material selection ensures a long service life and reliable performance even under demanding operating conditions.

Polychloroprene rubber is characterised by high resistance to oils, fats, solvents, and other chemical substances. It is also resistant to UV radiation and exhibits good ageing resistance, increasing its suitability for both indoor and outdoor applications. The gland is suitable for a wide range of installation scenarios, particularly in electrical installations, machine cabling, automation technology, or building automation.

Applications include cabling in enclosures, control and distribution boxes, and industrial plants where tight and mechanically stable cable guidance is required. The gland allows for easy installation, as it can be elastically adapted and inserted into the designated hole without tools. The precise fit ensures no gaps remain, which could allow dust, moisture, or other particles to enter.

Functions and equipment in detail include precise dimensioning for the intended application: the inner diameter of 20 mm allows for the passage of cables with a corresponding diameter, while the total length of 65 mm ensures sufficient insertion depth into the enclosure. The outer diameter of 20 mm ensures a secure fit in the drilled hole. The gland is not equipped with additional fastening elements or tools — installation is achieved solely through elastic fit.

Compatibility and accessories refer to use in conjunction with other components of the Helavia product range, particularly in switch boxes and distributors designed for gland installation. The gland is not specific to any particular accessory or brand and can be used in all installations supporting the specified dimensions.

Installation and mounting is performed by simply inserting the gland into the pre-drilled hole in the enclosure. The elastic shape of the material ensures the gland automatically adapts to the hole and provides a tight seal. No additional fastening or tools are required. Installation is quick and can also be carried out in tight or hard-to-reach areas.

Operational advantages include easy handling, high mechanical stability, and long service life. The gland protects cables from mechanical damage and prevents ingress of foreign particles, increasing installation reliability. The material quality ensures high resistance to environmental influences, improving maintenance-free operation and operational safety. The black colour is neutral and blends well into most technical environments.

The packaging unit is 100 pieces, suitable for larger installations or series mounting. The weight per piece is 0.66 g, indicating a compact and lightweight design. The packaging weight is 0.066 kg, highlighting its transport and storage friendliness.
