The product is a seal insert from the SKINTOP/DV-M25 series by Lapp, specifically designed for use in cable glands. It is offered in size M 25 and is finished in black. This seal insert is intended to seal unused connection points on electrical devices or machines, preventing unwanted moisture ingress. It is inserted into the seal of the SKINTOP® cable gland to protect the interior of the housing from moisture, particularly in areas where high humidity or temporary dampness may occur.

Applications

The seal insert is primarily intended for preparation during installation and for protecting unused connection points. It is used in electrical and automation technology, where permanent sealing of cable glands is required to ensure the functionality and service life of the electrical installation. Its use is particularly common in industrial environments where moisture or splashing water could endanger electrical components.

Functions and Features in Detail

The seal insert is designed as a replacement part for SKINTOP® cable glands and is inserted into the gland's seal. It prevents moisture from entering the interior of the housing through unused connection points. The black finish corresponds to the standard color for this series. The size M 25 refers to the internal diameter of the gland into which the seal insert fits. The shape and fit are designed to ensure a secure and tight connection.

Technology Explained Simply

The seal insert is made of an elastic material that conforms to the inner wall of the cable gland, ensuring a tight seal. The sealing effect is achieved through mechanical fit and the elasticity of the material, which compensates for surface irregularities under pressure. No additional adhesives or fastening elements are required — the insert is simply pushed into the gland's seal. The function is purely passive and requires no electrical or mechanical energy.

Compatibility and Accessories

The seal insert is specifically designed for use in SKINTOP® cable glands of size M 25. It is not suitable for other gland systems or different diameters. Compatibility is limited to the SKINTOP® series, particularly models that feature a seal designed to accommodate seal inserts.

Installation and Mounting

Installation is performed by simply inserting the seal insert into the seal of the SKINTOP® cable gland. No tools are required, and the insertion position is determined by the shape of the insert. Correct installation is ensured by the precise fit, with full insertion into the seal being necessary to achieve a tight seal. Installation takes place after the cable gland has been mounted on the device or machine.

Operational Advantages

Using the seal insert extends the service life of the electrical installation by protecting internal components from moisture. This reduces the risk of short circuits, corrosion, or other moisture-related damage. The simple handling and precise fit ensure reliable sealing without additional effort. Its use is especially beneficial in environments with high moisture exposure, where long-term protection is required.
