What Are Pneumatic Fittings?
Pneumatic quick-connect fittings are essential components in pneumatic systems. They connect, distribute, and transfer compressed air to power various pneumatic equipment and tools. These fittings are vital in industrial and automation settings to ensure system reliability and performance.
Comparison of Nut, Push-In, and Barbed Pneumatic Fittings:
| Feature | Push-In | Barbed | Nut |
| Use | Ideal for quick assembly and disassembly | Suitable for tight air-seal and safety | Ideal for adjustable tightness and airtight connections |
| Characteristics | The claw structure automatically clamps the pipe for quick connection | The push-in design, with a hook and knurled nut, provides a secure connection | Threaded, requires screwing in or out |
| Advantages | Fast assembly and disassembly, no special tools needed | Good airtightness, safe | Adjustable connection, higher versatility in pneumatic systems |
| Disadvantages | Not suitable for extreme pressures or high temperatures | Requires tools to tighten the knurled nut, heavier in weight | Requires additional sealing material, more complex connection process |
