PC4 pneumatic fittings for PTFE tube 3D printer
On a 3D printer, a worn fitting that no longer holds the PTFE tube in place causes extrusion to derail. These PC4 quick-connect fittings firmly grip the 4 mm tube and can be installed or removed with a single press, ensuring reliable filament flow.

Product details
In use, these small fittings solve a common issue with 3D printers. Screw on the fitting, push in the PTFE tube, and the ring locks it firmly in place: no more tube slipping back during printing. To remove it, simply press the ring and pull. No more clogs and under-extrusions caused by worn fittings, enjoy a clean filament path.
Compatibility and uses
These fittings accept a PTFE tube with an outer diameter of 4 mm, the standard for Bowden and direct drive 3D printers. Two models are available: the PC4-M6 (M6 thread, hotend side) and the PC4-01 (1/8" thread, extruder side). They are compatible with most FDM printers (such as Creality Ender and equivalents). Check your machine's thread before ordering.

Usage advice
The team's tip: cut the PTFE tube perfectly straight before pushing it in fully; this prevents filament micro-leaks.
Presentation
A pneumatic fitting may seem insignificant, but it ensures the tube does not move during printing. The clawed ring grips the PTFE and locks it, while the brass or stainless steel body withstands heat near the hotend. Replacing them as soon as they become loose prevents many failed prints.
Key features
- Firm hold: The ring locks the PTFE tube, preventing any backward movement during printing.
- Quick assembly: Push in to install, press to remove, no tool needed.
- Two thread options: PC4-M6 or PC4-01 depending on your machine.
- Durable: Brass or stainless steel body, suitable near the hot zone.
Who is it for?
For 3D printer owners whose tube fittings are worn or leaking. And for those who keep spare parts to avoid machine downtime.
