## Long description

The Ergom Polyamide Cable Gland Reducer DR 20M/16M is a professional-grade component engineered to facilitate the transition between different thread sizes in electrical cable management systems. Specifically designed to adapt an M20 entry point to an M16 cable gland, this reducer ensures that installers can maintain structural integrity and environmental protection when working with varying cable diameters. Constructed from high-quality polyamide, it offers robust mechanical strength and resistance to harsh environmental conditions, making it an essential part of any reliable electrical installation.
Advantages
This cable gland reducer provides a secure and stable connection that maintains the overall safety of the electrical system. Its polyamide construction is highly resistant to chemical agents, oils, and grease, ensuring longevity even in demanding industrial environments. The precise threading allows for quick and easy installation, reducing assembly time while ensuring a tight fit that prevents dust and moisture ingress. By using this component, you can effectively standardize your cable entry points without the need for complex modifications to your enclosures or junction boxes.
Suitable for
Adapting M20 threaded holes to M16 cable glands
Industrial control panels and electrical cabinets
Commercial wiring and infrastructure projects
Environments requiring chemical and mechanical resistance
This reducer may not be suitable for applications involving extreme heat or high-pressure steam, as polyamide materials have specific thermal limitations. It is also not intended for use in environments where the cable gland must withstand significant structural loads or heavy mechanical impacts that exceed the material's rated capacity.
Key specifications
Material: Polyamide
External thread: M20
Internal thread: M16
Application: Cable gland size reduction
Chemical resistance: High
To use the Ergom reducer, first ensure that the enclosure or junction box has an existing M20 threaded opening. Simply screw the reducer into the M20 port until it is firmly seated. Once the reducer is installed, you can proceed to attach your M16 cable gland into the internal thread of the reducer. Ensure that all connections are tightened appropriately to maintain the intended ingress protection rating of your electrical assembly.
What to consider before purchase
Verify that your enclosure entry point is M20
Confirm that your cable gland is M16
Check the environmental temperature range of your installation site
Ensure compatibility with the specific cable gland type being used
For optimal performance and safety, always ensure that the threads are clean and free of debris before installation. Do not overtighten the component, as this may damage the polyamide threads.
