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.
