Precision-engineered pneumatic connector featuring a 360° rotatable locknut for simplified installation in confined spaces. The dual-seal design combines metal-to-metal sealing (thread interface) with elastomer sealing (tube interface) for leak-free performance under pressure fluctuations. The anti-vibration collar prevents unintended disconnection in high-cycle applications.
- Robotic arm pneumatic tool changers
- CNC machine tool coolant line connections
- Semiconductor wafer handling vacuum systems
- Electric vehicle battery cooling circuits
- Packaging machine air knife assemblies
Installation protocol:
Hand-tighten locknut before final torque adjustment (recommended 0.7-1.2 N·m).
Always insert tubes perpendicularly until hearing an audible click. Perform
monthly collar inspections in high-vibration environments.
