Precision-engineered pneumatic connector featuring triple-locking mechanism (thread+collet+O-ring) for vibration-resistant tubing connections. The electroless nickel plating provides corrosion resistance in humid environments. Designed for zero-leak performance in high-cycle applications.
- Requires 8-10Nm torque during assembly (use backup wrench)
- Ideal for robotic arm pneumatic circuits (6-axis applications)
- Medical device gas delivery systems
- Packaging machine sensor air lines
- Semiconductor fab equipment
- High-frequency valve manifolds
Maintenance tip:
Replace O-rings every 500,000 cycles or 2 years (whichever comes first).
Use thread sealant only on male threads, never on compression surfaces.
