Pneumatic Fitting FAQs

When selecting pneumatic fittings, consider the following factors:

  • Connection Object: Tubing (flexible, rigid), equipment threaded ports, etc.
  • Tube Size: Outer or inner diameter of the tube.
  • Thread Specification: Metric (M), British Standard Pipe (G/BSPP, R/BSPT), National Pipe Thread (NPT), etc., and their sizes.
  • Working Pressure & Temperature: Ensure the fitting can withstand the system’s maximum operating pressure and temperature range.
  • Fluid Medium: Compressed air, vacuum, or other special gases/liquids; consider material compatibility.
  • Installation Space & Method: Straight, elbow, tee, push-in, threaded, etc.
  • Frequency of Use: Whether frequent disconnection is needed (consider quick-connect fittings).

We recommend consulting our product catalogs or contacting technical support for expert selection advice.

The main differences lie in the connection method and usage scenarios:

  • Quick-Connect Fittings (Push-in Fittings): Typically designed for one-hand operation, allowing rapid tube insertion and removal without tools. Ideal for applications requiring frequent disconnection or maintenance.
  • Standard Tube Fittings (e.g., Compression Fittings, Threaded Fittings): Usually require tools for tightening and installation, providing a more secure connection. Suitable for fixed connections, high-pressure, or vibration-prone applications.
  • Brass Fittings: Cost-effective, good conductivity, decent corrosion resistance, and good mechanical strength. One of the most widely used materials.
  • Stainless Steel Fittings: Excellent corrosion resistance (especially to many chemicals), good high/low-temperature performance, high strength, and high hygiene levels. Suitable for food, medical, chemical, and other demanding environments. Relatively higher cost.
  • Plastic Fittings: Lightweight, good corrosion resistance (better than metal for some chemicals), lower cost, and easy to install. However, strength and temperature/pressure resistance are generally lower than metal fittings.
  • Carbon Steel Fittings: High strength, lower cost, but poorer corrosion resistance, usually requiring surface treatment (e.g., galvanizing).

Material selection should consider the fluid medium, working environment, pressure/temperature requirements, and budget.

To ensure an airtight connection, pay attention to the following:

  • Correct Selection: Choose the fitting type and size that matches the tube and equipment interface.
  • Clean Ports: Ensure tube ends are cut squarely and are burr-free. Threads and sealing surfaces on fittings should be clean.
  • Proper Installation: For push-in fittings, ensure the tube is inserted fully. For threaded fittings, use appropriate sealant (e.g., PTFE tape, anaerobic sealant) and tighten to the recommended torque.
  • Avoid Over-tightening: Over-tightening can damage threads or seals.
  • Check Seals: Ensure O-rings or other seals are intact and correctly installed.
  • System Test: Conduct a pressure test after installation to check for any leaks.

Main Purpose: Pneumatic mufflers (silencers) are installed at the exhaust ports of pneumatic components (like solenoid valves, cylinders) to significantly reduce the noise generated by discharging compressed air, thereby improving the working environment and complying with occupational health and safety requirements.

How to Choose:

  • Port Thread Size: Must match the thread specification of the exhaust port.
  • Noise Reduction (dB): Select based on the required level of noise reduction.
  • Exhaust Flow Rate: Ensure the muffler’s flow capacity meets the maximum exhaust rate of the equipment to avoid excessive back pressure that could affect performance.
  • Material: Common materials include sintered bronze, engineering plastic, and stainless steel; choose based on environment and media.
  • Shape & Installation Space: Available in flat, conical, and throttling types, among others; select based on available space.
  • Working Pressure & Temperature: Ensure it’s within the system’s operating parameters.
