Metal Pneumatic Coupling 20.3 x 10 x 5.76 mm PC4 M6 for 4 mm PTFE Tube Filament Guidance Secure Fit for 3D Printers
This metal pneumatic coupling measuring 20.31 x 10.02 x 5.76 mm is designed for securely holding a PTFE tube with a diameter of 4 mm, which serves to guide the filament between the spool, feeder, and print head. Thanks to the M6 thread, the coupling is suitable for a wide range of 3D printers, especially where a Bowden feeding method is used. The solid metal construction ensures high durability, long lifespan, and stable holding even during prolonged printing.
The top part of the coupling is equipped with a flexible securing ring that allows for easy insertion and removal of the PTFE tube without damaging it. Inside the coupling, the tube is held firmly in place and will not come loose during operation, ensuring a consistent and smooth feed of the filament. This reduces the risk of print interruptions or irregular feeding, which are common causes of defective prints. Due to its compact shape, the coupling can be installed in tight spaces, such as at the entry of the filament path or on the printer body.
- Precise dimensions 20.31 x 10.02 x 5.76 mm for easy installation even in restricted spaces.
- Metal construction with M6 thread provides high strength, stability, and long lifespan.
- Designed for 4 mm PTFE tube, which guides filament from the spool to the feeder or print head.
- Secure holding due to the internal securing mechanism that prevents the tube from being pulled out during printing.
- Suitable for most 3D printers using Bowden filament guidance.
- Contents: 1x coupling.
This coupling is ideal for users looking to enhance the reliability and smoothness of filament feeding. It is suitable for both regular home use and workshops and operations where printing occurs regularly and stable material supply is emphasised. The simple screwing onto the M6 thread and pushing the tube in fully ensures quick installation without the need for further adjustments. Thanks to the robust material and precise processing, the coupling helps improve print quality, reduce the number of errors occurring during feeding, and ensures smooth operation of the printer even during long print jobs. It is a reliable and easy-to-use component that contributes to the seamless operation of any 3D printer.
