Advantages
The primary benefit of this reduction fitting is its superior build quality, which ensures excellent resistance to corrosion and mechanical wear. By utilizing nickel-plated brass, the fitting maintains structural stability even under challenging industrial conditions.

Suitable for
Industrial electrical control panels
Machine building and automation systems
Transitioning between different cable gland thread sizes
Applications requiring high mechanical stability
This fitting may not be suitable for applications involving extreme chemical exposure where specialized materials like stainless steel or plastic might be required. It is also not intended for use in environments where the thread standards differ from the specified PG metric system.
Key specifications
Material: Nickel-plated brass
External thread: PG29
Internal thread: PG21
Application: Cable gland reduction
To install the fitting, simply screw the external PG29 thread into the corresponding housing or enclosure port. Once secured, the internal PG21 thread allows for the attachment of a smaller cable gland. Ensure that the threads are properly aligned before tightening to prevent cross-threading and to maintain the specified mechanical connection.
What to consider before purchase
Verify that your existing enclosure port is PG29
Confirm that the cable gland you intend to use is PG21
Check the environmental conditions to ensure nickel-plated brass is appropriate for your specific application
For optimal performance and safety, ensure that the fitting is tightened to the manufacturer's recommended torque specifications and that all seals are correctly seated to maintain the intended ingress protection rating of your cable gland assembly.
