Push-fit pneumatic connector for PTFE Bowden tube
Pneumatic tube connectors or Bowden tube connectors are essential in day-to-day 3D printing. They are designed to facilitate robust and secure connection of pneumatic tubing, typically at the extruder inlet.
These stainless steel and plastic connectors are compatible with 4 mm (PC4) and 6 mm (PC6) outer diameter pneumatic tubing commonly used in all models of FDM 3D printers, depending on the filament used by each model.
For 1.75 mm filament 3D printers, the PTFE tube usually has a 4 mm outer diameter (2 mm inner diameter), and for 2.85 mm filament, it usually has a 6 mm outer diameter (4 mm inner diameter). The PC4-M5 and PC4-M6B models have M5 and M6 metric threads, respectively, and are designed for 1.75 mm filament, just like the PC4-01 model, which has an M10 thread.
A push-fit connector for PTFE Bowden tubes ensures secure, tool-free filament feeding.
