PC4 M6 Pneumatic Valve Head 10Pcs for 3D Printer

### Reliable PTFE Tube Connection for 3D Printers This PC4-M6 pneumatic connector securely holds 4mm OD PTFE tubes in place at extruders, hotends, and AMS hubs. Prevents tube loosening that can cause filament jams and failed prints. ### Durable PTFE Construction Heat Pressure Resistant Made from high quality PTFE material. Resists heat (up to ~260°C), pressure, and aging. More durable than ordinary plastic connectors that crack and degrade over time. ### Quick Push in Pull out Installation Features a quick release design with blue release ring. Insert the PTFE tube firmly until it clicks into place. Press the release ring to remove the tube. No tools required for installation or removal. ### Secure Fit with 10 Blue Release Caps Included Each connector comes with a matching blue release cap. The cap protects the release mechanism and provides a clear visual indicator of the connection status. 10 sets per package. ### Universal Compatibility with 4mm PTFE Tubes Compatible with all 3D printers using 4mm outer diameter PTFE tubing. Works with Creality, Bambu Lab, Anycubic, Prusa, Voron, and other FDM printers with M6 threads.
