General
Colour	Black

The DG-TPE 13.5 membrane grommets from Ses-Sterling are black-coloured, flexible passage elements made of thermoplastic elastomer (TPE), specifically designed for use in installations where cables or lines must be routed through wall or ceiling openings. These rubber grommets serve as passage grommets and enable a secure, tight, and simultaneously elastic routing of cables, while also providing mechanical protection. The designation DG-TPE 13.5 refers to the specific design and nominal size, which is relevant for precise adaptation to the respective passage opening.

Applications

The DG-TPE 13.5 membrane grommets are particularly suitable for use in electrical installations where a tight and flexible cable routing is required. They are frequently used in building and industrial technology to route cables through wall or ceiling openings without compromising the tightness of the components. The use of TPE as a material ensures high flexibility and elasticity, allowing the grommets to be easily inserted into the opening while applying a firm but not excessive tension on the cable. The black colour corresponds to the standard in electrical installations and blends visually into most installation scenarios.

Functions and Equipment in Detail

The membrane grommets are made of an elastic TPE material, offering high mechanical load capacity and resistance to wear. The shape is designed to elastically adapt to the cable surface, ensuring secure guidance. The nominal size of 13.5 mm refers to the inner diameter specification, which is crucial for selecting the correct grommet size to achieve optimal fit. The grommets are supplied as individual units and can be inserted one by one into the designated opening. The packaging unit contains 100 pieces, suitable for larger installations or series mounting.

Technology Explained Simply

TPE stands for thermoplastic elastomer, a plastic that combines the properties of thermoplastics (such as meltability when heated) with the elasticity of elastomers (like rubber). This material is particularly suitable for applications requiring high flexibility, resistance to mechanical stress, and long service life. The membrane grommets utilise these properties to enable a tight and simultaneously elastic cable routing. The black colour is not only visually consistent but also functional, as it is UV-resistant and thus does not discolour or degrade even with prolonged exposure to sunlight. The weight specification of 1.8 g per piece indicates that this is a lightweight yet robust component, easy to handle.

Compatibility and Accessories

The DG-TPE 13.5 membrane grommets are specifically designed for use in installations with cable passages. They are compatible with standard installation systems where an elastic and tight cable routing through wall or ceiling openings is required. The grommets can be used with various cable types, as long as the cable diameters fall within the specified fit range.

Mounting and Installation

Installation is carried out by simply inserting the membrane grommets into the designated opening. The elastic shape of the TPE material ensures that the grommets adapt to the cable surface and provide secure, tight guidance. No additional tool support is required, as the grommets can be easily inserted into the opening due to their elasticity. Installation typically does not require additional adhesives or fasteners, as the elastic tension is sufficient to hold the grommets in place.

Operational Advantages

Using membrane grommets made of TPE offers several operational advantages: the high elasticity ensures tight and flexible cable routing, reducing mechanical stress and extending cable lifespan. Material strength ensures long service life, even under stress from temperature fluctuations or mechanical loads. The black colour is UV-resistant and visually matches most installation scenarios. The lightweight construction facilitates handling and installation, especially in larger installations involving multiple grommets.
