Industrial Applications

1. High-Flow Pneumatic Manifold Tubing Connections

Integrating main air supply lines to pneumatic manifolds in automated packaging systems requiring high volumetric flow rates.

Problem Solved

Distributing bulk compressed air from main lines to local valve islands. The 10 mm nominal size and 16 mm tubing port provide a high-flow pathway with minimal restriction, while the R1/2 pre-coated thread prevents leaks at the critical manifold interface under dynamic loads up to 8 bar.

2. Automated Cleanroom Electronic Assembly Lines

Routing pneumatic control lines for actuators inside high-grade electronics and semiconductor manufacturing cleanroom chambers.

Problem Solved

Standard fittings can release particles or paint-wetting impairment substances (PWIS/LABS) that ruin delicate electronic components. The NPQE-D-R12-Q16-P5 conforms to VDMA24364 zone III (LABS-free) and is certified for Cleanroom Class 4 (ISO 14644-1), ensuring a zero-defect manufacturing environment.

3. Industrial Vacuum Handling and End-of-Arm Tooling

Linking primary vacuum generators to large-diameter suction cups (such as the Festo ESS-40-CS) for handling sheets of metal or wood in robotic work cells.

Problem Solved

Handling heavy objects via vacuum requires reliable seal integrity under negative pressures. Since this fitting supports a vacuum down to -0.95 bar (-0.095 MPa), it prevents air ingress at the joints, ensuring the vacuum system maintains maximum holding force without unexpected dropping hazards.
