General
Colour	Black

The Ses-Sterling membrane grommets DG-TPE 21 black are passage grommets made of thermoplastic elastomer (TPE), specifically designed for use in installations where a flexible and simultaneously tight connection of cables or conduits through components such as wall or ceiling penetrations is required. The product is offered under manufacturer number 01440050010 and is available in the colour black. The grommets serve as cable protection and enable a tight connection without additional sealing materials, with the membrane structure providing elastic adaptation to different cable diameters.

Applications
The membrane grommets DG-TPE 21 are suitable for use in electrical and electronic installations, particularly in areas where mechanical and electrical insulation as well as sealing against dust and moisture is required. They are used in building installations, industrial and machine engineering technology, and electrical installations where cables are routed through walls, ceilings or other components. The grommets are intended for indoor use, with the TPE material composition providing high flexibility and resistance to mechanical stress.

Functions and Equipment in Detail
The grommets are made of an elastic TPE material, which exhibits high extensibility and resilience. The membrane structure allows for elastic adaptation to various cable diameters, achieving a tight connection without additional sealing materials. The black colour is standard and meets common requirements in electrical installations. The grommets are designed for easy installation, ensuring secure fastening through screwing into the penetration.

Technology Explained Simply
The TPE (Thermoplastic Elastomer) material combines elastic properties with thermoplastic processability. It provides high flexibility while maintaining mechanical stability. The membrane structure of the grommets ensures that the material elastically deforms when the cable is inserted and then forms a tight seal around the cable. This prevents dust, moisture or other particles from entering the installation.

Compatibility and Accessories
The membrane grommets DG-TPE 21 are designed for use with standardised penetrations in electrical installations. They are not specifically designed for particular brands or models, but adapt to various penetration geometries due to their elastic structure. The grommets are to be understood as individual components inserted into existing penetrations.

Installation and Mounting
Installation is carried out by simply inserting the grommet into the penetration and then screwing it in. The elastic membrane automatically adapts to the cable diameter, creating a tight connection. No additional tools or sealing materials are required. The grommets are designed for manual installation, ensuring secure and tight fastening. The packaging contains 100 pieces, suitable for larger installations.

Operational Advantages
The DG-TPE 21 membrane grommets provide a reliable and tight connection of cables through components. The elastic membrane structure ensures secure sealing against dust and moisture, thereby increasing the lifespan of the installation. The simple installation without additional sealing materials reduces labour effort and error susceptibility. The TPE material offers high flexibility and resistance to mechanical stress, enhancing reliability in operation. The grommets are available in black, meeting requirements in electrical installations.
