PC4-M6 fitting for 4mm PTFE tubing and M6-threaded parts

The Stainless Steel Pneumatic Push-In Fitting PC4-M6 is a connector made to securely attach 4mm outer diameter PTFE (Teflon) tubing to components with M6 threading. This type of fitting is commonly used in 3D printers and pneumatic systems where a secure tube connection and smooth tube path are important.

Key features of the stainless steel push-in fitting

• Durable stainless steel construction: The stainless steel body offers strong resistance to corrosion and wear for long-lasting performance.
• Quick push-in connection: The push-in mechanism allows fast installation and removal of PTFE tubing without sacrificing grip.
• Straight-through tube path: An internal diameter of approximately 4.1-4.2mm lets the PTFE tube pass through smoothly, which helps minimize resistance and potential filament jams.

Where a PC4-M6 pneumatic fitting is commonly used

This pneumatic push-in fitting is particularly suitable for 3D printers with Bowden extruder systems. It is also a practical choice for other pneumatic setups that use 4mm PTFE tubing and M6-threaded connection points.

Why the straight-through design matters in Bowden setups

A smooth tube path helps maintain consistent filament movement through the PTFE tube. For Bowden-style 3D printers, that can help reduce friction at the fitting and support more reliable filament feeding.
