PC4-M10 Pneumatic Coupler Connector – 4mm Straight Fitting for 3D Printer Bowden Extruder in Pakistan

Overview

The PC4-M10 Pneumatic Fitting is a premium metal push-to-connect coupler widely used in 3D printers and industrial pneumatic systems. It features a convenient quick-release mechanism that firmly grips 4mm Outside Diameter (OD) PTFE tubing while providing a sturdy M10 (10mm) male thread connection on the other end. Made of high-quality brass and stainless steel teeth, this coupler prevents the Bowden tube from slipping out during fast retractions, reducing the chances of under-extrusion and filament jams.

Key Features

• Quick-Release System: Simply press the black or blue plastic release ring down to instantly slide the PTFE tube in or out.

• Aggressive Internal Grip: Stainless steel lock claws inside the coupler ensure the tube stays firmly in place under high pressure.

• Thread Precision: M10 metric thread fits perfectly into standard aluminum extruder blocks, heatsinks, and custom feeder mechanisms.

• 3D Printer Essential: The standard replacement part for popular desktop 3D printers like the Creality Ender 3 series, CR-10, Anycubic, and Prusa clones.
