Push-Fit Connector for 1.75 mm Filament
This pack contains two M6 push-fit tube fittings designed for 3D printers. Each fitting accepts a 4 mm OD PTFE tube and guides 1.75 mm filament toward the extruder. The brass and plastic construction provides a secure, leak-free seal. Installation is tool-free and completed in seconds.
For Direct-Drive or Bowden Extruder Builds
These fittings suit hobbyists and technicians assembling or repairing printers that use M6 threaded hot-ends with 4 mm tubing. They will not work with 3 mm filament paths, metric threads other than M6 × 1.0, or printers that require a different tube diameter. Buyers needing alternative thread sizes or larger bore tubing should look elsewhere.
M6 × 1.0 Thread Pitch Decides Fit
The single specification that determines compatibility is the M6 thread with a 1.0 mm pitch. Verify that your hot-end or extruder body has exactly this thread before purchasing. Overall height is 20 mm and the blue release collar has a 4 mm inner diameter for the tube.

Questions about this item
Should I choose the 2-piece pack or buy singles?
The listing includes exactly two push-fit fittings in one pack; there is no single-unit option shown.
What does the 4 mm inner diameter mean for my 1.75 mm filament setup?
The 4 mm bore accepts standard 4 mm OD PTFE tubing that guides 1.75 mm filament from extruder to hot-end.
Does the M6 × 1.0 mm thread limit which printers I can use this on?
The fitting screws into any M6 × 1.0 mm threaded port, a common size on many direct-drive and Bowden extruders.
