Festo Brass Pneumatic Quick Connect Coupling, CK-3 Male CK-3 8mm Coupling Socket

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.

• 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

• 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

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

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

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

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