Industrial Applications

1. Semiconductor Wafer Handling and Cleanroom Assembly

High-precision semiconductor packaging and wafer handling lines require pneumatic components that do not contaminate the sterile air environment.

Problem Solved

Standard fittings can shed particles or outgas, contaminating semiconductor wafers. This fitting is certified to ISO 14644-1 Class 4 cleanroom suitability and has VDMA24364 zone III LABS/PWIS conformity, ensuring it introduces zero paint-wetting impairment substances and meets strict cleanroom particulate levels.

2. Automated Vacuum Pick-and-Place Systems

In electronic component assembly, vacuum suction cups are used to pick up and place small components. This requires fittings that can hold a consistent negative pressure.

Problem Solved

The straight push-pull fitting reliably holds vacuum levels down to -0.095 MPa (-0.95 bar). The high-durability NBR seals and stainless steel tubing clamp prevent vacuum leaks, maintaining stable suction forces during high-speed packaging runs.

3. Factory Automation Pneumatic Manifold Connections

Distribution of compressed air within automated machinery control panels to pilot solenoid valves.

Problem Solved

Traditional threaded fittings require messy PTFE tape application, which can cause internal contamination if tape shreds enter the pneumatic line. The pre-applied PTFE coating on the R3/8 male thread allows direct, safe, and speedy mounting with external and internal hex tools in compact manifold enclosures, operating safely up to 8 bar.
