Precision-engineered pneumatic connector featuring triple-seal technology (radial seal, axial seal, and thread seal) for leak-free performance in high-vibration environments. The rotating locknut design enables 360° adjustable orientation post-installation while maintaining seal integrity. Compatible with polyurethane and nylon tubing (hardness range 80-94 Shore A).
- Robotic arm pneumatic circuits requiring flexible routing
- CNC machine tool coolant line connections
- Semiconductor manufacturing gas delivery systems
- Mobile hydraulic equipment with frequent hose reconfiguration
- High-cycle automation stations with vibration damping needs
Installation protocol:
(1) Insert tube fully until "click" engagement (2) Hand-tighten locknut (3) Final tighten with wrench
at marked flat surfaces (4) Perform 3x pressure cycle test (0→1.0MPa) before full operation.
Never reuse sealing rings.
