## Long description

The Lapp SKINDICHT MR-M is a high-quality brass lock nut designed to provide a secure and reliable connection for cable gland installations. This reducer nut allows for the seamless integration of cable glands with smaller connection threads into existing larger threaded holes, making it an essential component for versatile electrical installations. Crafted from durable brass, this silver-colored component ensures long-lasting performance and mechanical stability in demanding industrial environments.
Advantages
The primary advantage of the SKINDICHT MR-M is its ability to bridge the gap between different thread sizes, specifically from M63 to M40, which offers significant flexibility during equipment assembly. Its robust brass construction provides excellent resistance to environmental factors and mechanical stress, ensuring that cable connections remain tight and protected over time. The precision engineering of the threads guarantees a smooth installation process, reducing the risk of cross-threading and ensuring a professional finish for any electrical project.
Suitable for
Industrial machinery and control cabinets
Electrical cable management systems
Adapting existing threaded holes to smaller cable gland sizes
Equipment assembly requiring thread reduction
This lock nut may not be suitable for applications requiring non-metallic or plastic components due to specific chemical resistance or weight requirements. It is also not intended for use in environments where brass is incompatible with the surrounding materials or where specialized high-pressure sealing beyond standard cable gland requirements is necessary.
Key specifications
Material: Brass
Thread sizes: M63 (outer) to M40 (inner)
Color: Silver
Quantity: 10 pieces per pack
To use the Lapp SKINDICHT MR-M, simply insert the reducer into the existing M63 threaded hole of your enclosure or machine housing. Once seated, screw your M40 cable gland into the inner thread of the reducer. Ensure that both the reducer and the cable gland are tightened sufficiently to maintain the integrity of the connection and the required ingress protection rating of your assembly.
What to consider before purchase
Verify that the existing hole size is M63 and the required cable gland size is M40
Ensure the brass material is compatible with your specific industrial environment
Confirm the quantity required for your project, as this pack contains 10 pieces
For optimal performance, ensure that the threads are clean and free of debris before installation. Always use appropriate tools to tighten the lock nut to prevent damage to the threads or the enclosure surface.
