Adaptaflex Black, Conduit Fitting, 21 mm Nominal Size, PG16, Polyamide 66, Black IP67, IP69K, IP68, IP66 rating

ABB ASF Series Conduit Fitting, 21mm Nominal size, Black - ASF21/PG16/90 & AWB21

This conduit fitting provides a secure Interface for cable entry and routing in industrial installations. Designed for demanding environments, it offers robust protection against dust and water ingress while maintaining compatibility with standard PG16 threaded systems. The device is finished in black and is intended for use where sealed electrical connections are required.

Features & Benefits

• IP67 protection for temporary immersion and dust exclusion
  IP68 resistance for continuous submersion applications
  IP69K rating for high-pressure, high-temperature washdowns
  Constructed from polyamide66 for chemical and impact resilience
  Nominal 21mm size to accommodate common cable diameters
  PG16 thread to fit standard industrial conduit entries

**Applications**

• Suitable for automation control cabinet cable routing
  Ideal for electrical junction boxes in harsh environments
  Used for wiring penetrations on machinery requiring washdowns
  Can be used with sensor and actuator cabling in factories
  Used for outdoor electrical enclosures exposed to moisture

What material properties affect mechanical durability?

The polyamide66 composition delivers good tensile strength and resistance to many oils and greases, helping maintain mechanical integrity under vibration.

How does the finish contribute to performance?

The black finish reduces light reflection and provides a consistent surface for sealing interfaces, aiding Visual inspection and installation alignment.

Which environmental protections are provided simultaneously?

The device combines dust-tight sealing with multiple liquid ingress ratings, enabling use across immersion, continuous submersion and high-pressure wash conditions.

What thread standard should mating components match?

Mating parts must accept a PG16 threaded connection to ensure proper engagement and sealing.

Is this fitting appropriate for cable diameters around 21 mm?

The nominal size is 21 mm, matching commonly used cable diameters in industrial wiring runs.
