CNC Pneumatic Threaded Fittings for Automotive & Industrial Air Systems
Overview of Pneumatic Threaded Fittings
Pneumatic threaded fittings are essential components in any compressed air system, connecting valves, hoses, actuators, and manifolds with a secure, leak-proof seal. These components are vital for applications where airflow precision and mechanical stability are critical.
Key Benefits of Our CNC Pneumatic Fittings
Leak-Free Thread Engagement
All fittings are CNC-machined with tight tolerance control to ensure a smooth, repeatable thread fit, reducing the chance of leaks during operation.
Corrosion-Resistant Materials
We use stainless steel, brass, or aluminum with nickel or anodized finishing to ensure durability, even in harsh environments or outdoor systems.
Universal Thread Compatibility
Available in BSP, NPT, and metric threading, making them compatible with global pneumatic standards and equipment.
Common Applications Across Industries
Automotive Air Systems
From electric vehicle battery cooling modules to commercial truck brake lines, pneumatic connectors play a vital role in ensuring sealed airflow under pressure.
Industrial Automation Lines
Used to connect air cylinders, valves, and robots in factories for precise actuation and flow control.
Compressed Air Management
Installed in air compressor units, filters, pressure regulators, and line couplers for secure joint performance.
Comparison: CNC Fitting vs Generic Cast Fitting
| Feature | CNC Threaded Fitting | Generic Fitting |
|---|---|---|
| Thread Accuracy | High | Medium |
| Leakage Rate | Low (<0.3%) | High (>2.5%) |
| Corrosion Resistance | Excellent | Moderate |
| Installation Ease | Smooth & Consistent | Variable |
How Our Fittings Improve Pneumatic Systems
Minimized System Downtime
Reliable fittings reduce leak-related failures and service interruptions.
Faster Assembly Times
Consistent threading and dimensions enable rapid installation, even on automated lines.
Reduced Maintenance Costs
Durable materials and tight seals lower repair frequency and part replacement needs.
Manufacturing Process for Premium Quality
Step 1: CNC Precision Turning
Using high-speed Swiss-type or multi-axis CNC lathes to form accurate outer and inner profiles.
Step 2: Thread Forming & Inspection
Threads are rolled or cut to international standards and tested with calibrated plug gauges.
Step 3: Surface Treatment
Finishing processes like nickel plating or anodizing enhance corrosion resistance.
Step 4: Final QC & Packaging
Each batch undergoes dimensional inspection and leak testing before export packaging.
Customer Success Story: EV Brake Module Supplier
A European Tier 2 automotive supplier replaced outdated zinc connectors with our stainless steel CNC pneumatic fittings. Over 8,000 units were deployed in brake modules with zero field failures after 12 months.
