Selecting Pneumatic Fittings for Automation Systems

Pneumatic system reliability starts with the right fittings. Consider pressure rating, tube compatibility, and environmental factors before specifying components for your automation line.

Push-to-Connect vs. Compression

Push-to-connect fittings offer the fastest installation and are ideal for prototyping and modular automation. Compression fittings provide higher vibration resistance for mobile and heavy-duty applications.

Tube Material Compatibility

Polyurethane, nylon, and PTFE tubing each require fittings designed for their outer diameter tolerance and temperature range.

Environmental Considerations

• Food & beverage: Specify FDA-compliant materials and washdown-rated finishes
• Clean rooms: Low-particulate composite bodies reduce contamination risk
• High vibration: Use fittings with collet lock rings and support brackets

Sizing & Flow

Undersized fittings create pressure drop and slow actuator response. Size for peak flow demand, not average consumption.
