## Long description

The Lapp Skindicht KUK PG21 / PG16 Polyamide Reducer is a high-quality industrial component designed to facilitate the transition between different thread sizes in cable management systems. This durable reducer allows for the installation of cable glands with smaller connection threads into existing larger threaded holes, providing a versatile solution for complex electrical setups. Manufactured from glass fibre-reinforced polyamide, it offers exceptional mechanical stability and long-term reliability in demanding environments.
Advantages
This reducer provides a seamless and secure connection, ensuring that cable glands remain firmly in place even under mechanical stress. Its glass fibre-reinforced polyamide construction guarantees high impact resistance and durability, making it suitable for various industrial applications. By enabling the use of smaller glands in larger openings, it simplifies installation processes and reduces the need for specialized drilling or custom housing modifications, ultimately saving time and resources during assembly.
Suitable for
Industrial electrical installations
Control cabinet manufacturing
Machine building and automation systems
Transitioning between PG21 and PG16 threaded ports
When it may not be suitable
This component is specifically designed for PG thread standards and will not be compatible with metric or NPT threaded systems. It is intended for use in standard industrial environments and may not be appropriate for extreme high-temperature applications or environments requiring specialized chemical resistance beyond the properties of standard polyamide.
Key specifications
Material: Glass fibre-reinforced polyamide
Thread sizes: PG21 (external) to PG16 (internal)
Colour: Grey
Design: Single-piece construction
How to use
To install the reducer, simply screw the external PG21 thread into the existing threaded hole of your enclosure or machine housing. Once securely tightened, the internal PG16 thread is ready to accept a standard PG16 cable gland. Ensure that the threads are aligned correctly before tightening to prevent cross-threading and to maintain the integrity of the connection.
What to consider before purchase
Verify that your existing housing port is PG21 and your cable gland is PG16
Ensure the operating environment is compatible with polyamide materials
Check if additional sealing washers are required for your specific ingress protection needs
Usage recommendations
For optimal performance and to maintain the mechanical integrity of your installation, ensure the reducer is tightened to the manufacturer's recommended torque. Avoid over-tightening, which could potentially damage the polyamide threads.
