KQ Series Pneumatic Fittings - Product Details

KQ Series Pneumatic Fittings: Reliable Connections for Pneumatic Systems

The KQ series pneumatic fittings are engineered for efficient and secure air transmission in industrial and automation applications. With a focus on ease of use, durability, and versatility, these fittings are ideal for connecting pneumatic tubes, cylinders, valves, and other components, ensuring stable performance in diverse working environments.

Key Features

  • Tool-Free Installation: Compact and lightweight design enables quick, tool-less assembly, significantly reducing installation time and labor costs.
  • Superior Sealing Performance: Precision-machined structure with high-quality sealing materials prevents air leakage, ensuring reliable operation of pneumatic systems.
  • Durable Construction: Nickel-plated brass body offers excellent corrosion resistance and wear resistance, suitable for harsh industrial conditions.
  • Wide Size Compatibility: Compatible with PU/nylon pneumatic tubes with outer diameters (OD) ranging from 4mm to 16mm, meeting various pipeline requirements.
  • 360° Rotatable Connection: Allows flexible pipeline layout, avoiding tube twisting and facilitating installation in confined spaces.
  • Stable Pressure Resistance: Working pressure range of 0-1.0MPa (0-145PSI), suitable for most low-to-medium pressure pneumatic applications.
  • Low Air Flow Resistance: Optimized internal structure minimizes air flow loss, ensuring efficient transmission of compressed air.

Application Scope

  • Industrial Pneumatic Systems: Perfect for matching with cylinders, air valves, air compressors, and vacuum generators in pneumatic control circuits.
  • Automation Equipment: Widely used in packaging machinery, printing machinery, conveying systems, automated assembly lines, and robotic arms.
  • Machinery Manufacturing: Applied in CNC machine tools, textile machinery, plastic processing equipment, and food processing machinery.
  • Automotive Industry: Used for pneumatic pipeline connections in automobile assembly lines, painting lines, and testing equipment.
  • Medical & Laboratory Equipment: Suitable for low-pressure pneumatic control systems in medical devices, laboratory instruments, and analytical equipment.
  • Electronic & Electrical Industry: Used in pneumatic components of electronic product assembly equipment and semiconductor manufacturing equipment.
