## Long description

The Lapp Skindicht KU Polyamide Reducer is a high-quality component designed to facilitate the transition between different thread sizes in cable management systems. Specifically engineered to adapt a PG21 threaded hole to a PG13.5 cable gland, this reducer ensures a secure and professional installation in various industrial and electrical environments. Manufactured from durable, glass fibre-reinforced polyamide, it provides excellent mechanical stability and long-lasting performance.
Advantages
This reducer offers significant versatility by allowing the use of smaller cable glands in larger existing threaded openings, which simplifies system design and maintenance. The glass fibre-reinforced polyamide construction ensures high resistance to mechanical stress and environmental factors, maintaining a reliable connection over time. Its grey finish provides a clean, professional appearance suitable for standard industrial enclosures and control cabinets.
Suitable for
Industrial control panels and electrical enclosures
Machinery and equipment manufacturing
Transitioning between different thread standards in cable routing
Applications requiring mechanical stability and secure cable gland mounting
This component may not be suitable for high-temperature environments exceeding the thermal limits of polyamide or for applications requiring metallic shielding or extreme chemical resistance. It is intended specifically for PG-threaded systems and cannot be used with metric or NPT thread types.
Key specifications
Material: Glass fibre-reinforced polyamide
Thread size transition: PG21 to PG13.5
Colour: Grey
Quantity: 1 piece per pack
To install the reducer, simply screw it into the existing PG21 threaded opening of your enclosure or junction box. Once firmly seated, the PG13.5 cable gland can be threaded into the internal side of the reducer. Ensure that the threads are aligned correctly to prevent cross-threading and tighten to the manufacturer's recommended torque to maintain the integrity of the connection.
What to consider before purchase
Verify that your existing enclosure hole is PG21 and your cable gland is PG13.5
Check if the environmental conditions are compatible with polyamide material
Ensure sufficient space is available for the added length of the reducer
For optimal performance and safety, always ensure that the cable gland is properly tightened and that the assembly is inspected periodically for any signs of mechanical wear or loosening due to vibration.
