Product information

Description

The Lapp SKINDICHT BL-M M20 brass plug is a professional-grade component engineered to securely seal unused threaded holes in electrical enclosures, junction boxes, and housings. Constructed from high-quality brass, this blind plug provides a robust and reliable barrier against environmental factors, ensuring the integrity of your electrical systems. Its design allows for quick and efficient installation, making it an indispensable part of industrial cable management and electrical infrastructure projects.

Advantages

The primary advantage of the SKINDICHT BL-M is its durable brass construction, which offers superior mechanical strength and resistance to corrosion compared to plastic alternatives. This plug ensures a tight and secure fit, maintaining the protective rating of your enclosure by preventing the ingress of dust and moisture. Its standardized M20 thread size ensures compatibility with a wide range of industrial housings, while the simple design allows for easy assembly using a standard screwdriver, saving time during installation and maintenance.

Suitable for

Sealing unused M20 threaded ports in electrical enclosures
Protecting internal components from dust and moisture in industrial environments
Closing pre-threaded holes in junction boxes and control panels
Professional cable management and electrical installation setups

When it may not be suitable

This plug is designed specifically for M20 threaded holes and will not fit ports with different thread sizes or types. It is intended for use in standard industrial enclosures and may not be appropriate for specialized applications requiring extreme chemical resistance or specific high-pressure ratings beyond its standard specifications.

Key specifications

Thread size: M20
Material: Brass
Installation method: Screwdriver
Application: Closing pre-threaded holes

How to use

To install the Lapp SKINDICHT BL-M plug, simply align the threaded portion with the unused M20 hole in your enclosure. Insert the plug and use a standard screwdriver to rotate it clockwise until it is firmly seated. Ensure that the plug is tightened sufficiently to create a secure seal, providing the necessary protection for the internal components of your housing.

What to consider before purchase

Verify that the enclosure hole is M20 threaded
Ensure the brass material is compatible with the environment of the installation
Check the required ingress protection level for your specific application

Usage recommendations

For optimal performance and to maintain the integrity of the seal, ensure the threaded hole is clean and free of debris before installation. Do not overtighten the plug to avoid damaging the threads of the enclosure.
