Festo KD2-CK-3 Series Pneumatic Quick Connect Coupling, 12 Bar Maximum Operating Pressure, Brass Material - KD2-CK-3

This pneumatic quick-connect coupling provides a robust connection solution for compressed air systems in industrial settings. It links an 8mm hose via a barb to a male threaded port conforming to the CK-3 thread standard, enabling straightforward connection and disconnection of air lines. Constructed from brass, it is intended for use across a range of ambient temperatures and is suitable for installations requiring adherence to recognised air quality standards.

Features and Benefits:

• Rated to operate at 12 bar delivering stable system pressure handling
• Brass construction offering corrosion resistance and durability
• Compatible with 8mm hose barb for secure hose retention
• Male CK-3 threaded interface enabling standardised mating
• Usable between -10°C and +60°C for varied ambient conditions

Applications

• Suitable for workshop compressed air distribution systems
• Ideal for pneumatic tool hook-ups on production lines
• Used with temporary air supply arrangements for maintenance
• Can be used for connection points in pneumatic test rigs

What material is used for the connector body and why is it chosen?

The fitting is made from brass, selected for its wear resistance and suitability for repeated make-and-break cycles in air applications.

How does temperature range affect where it can be installed?

The specified -10°C to +60°C range defines safe ambient conditions for reliable sealing and material performance without accelerated degradation.

Is the thread compatible with standard CK-3 female ports?

Yes, the male thread follows the CK-3 thread standard so it mates with matching CK-3 female connectors.

What air quality standard does it relate to and what does that imply?

It aligns with ISO 8573-1:2010, indicating conformity with recognised particulate and contaminant classifications for compressed air systems.
