The Helavia DA 120/180/40 black from Ses-Sterling are gland seals made of polychloroprene rubber, designed for use in electrical and installation technology. These gland seals provide secure and tight guidance of cables or conduits through drill holes in wall or ceiling structures, particularly in areas where mechanical protection and a certain degree of elasticity are required. The seals are black and made of an elastic, durable material that adapts to the shape of the opening and ensures a tight seal.

Applications
These gland seals are used in electrical installations, particularly for routing cables through wall or ceiling openings. They are suitable for indoor use where mechanical protection for cables is necessary, for example in residential and commercial spaces, office buildings, or industrial facilities. The seals are designed for drill holes with a diameter of 120 mm to 180 mm and allow the passage of cables with a maximum diameter of 40 mm. The use of polychloroprene rubber ensures high flexibility and durability under normal operating conditions.

Functions and Features in Detail
The gland seals are molded parts made of polychloroprene rubber, a material known for its elasticity, resistance to mechanical stress, and durability against environmental influences. The seals are black and enable secure, tight cable guidance through drill holes. The shape is designed to elastically adapt to the geometry of the hole and provide mechanical protection for the cables. The maximum cable diameter specification of 40 mm refers to the diameter of the conductors being routed through the seal.

Technology Explained Simply
The gland seals are made of an elastic material that deforms under pressure and ensures a tight fit in the drill hole. Polychloroprene rubber offers high mechanical strength and resistance to mechanical stress, making the seals suitable for use in electrical installations. The black color is standard and contributes to visual harmony with other installation components.

Compatibility and Accessories
The Helavia DA 120/180/40 black are designed for drill holes with a diameter range of 120 mm to 180 mm and allow the passage of cables with a maximum diameter of 40 mm. They are intended for use as individual components and can be combined with other installation elements such as cable protection conduits, wall penetrations, or cable ties. There are no specific accessories directly associated with this item, as the seals are standard components in electrical installations.

Installation and Mounting
Installation is carried out by simply inserting the seal into the pre-drilled hole. The elastic shape of the material ensures that the seal adapts to the hole and provides a tight fit. Cables are routed through the central opening of the seal. No additional fastening is required, as the elastic material holds the seal securely in place. The installation can be performed without tools and is quick and easy to carry out.

Operational Advantages
The gland seals offer simple, reliable, and tight cable guidance through wall or ceiling openings. The polychloroprene rubber material ensures high mechanical strength and long service life. The seals are easy to install and require no additional fastening elements. The black color blends visually into most installation environments. The seals are available in a pack of 100 pieces, making them suitable for larger projects.
