Pneumatic clutch PC4-01 (G 1/8")

PC4-01 pneumatic coupling (G 1/8") – for Bowden PTFE tubing

High-quality PC4-01 pneumatic coupling designed for attaching PTFE (Bowden) tubing with a diameter of 4 mm.

It is mainly used on the heatsink of the hotend in 3D printers with a Bowden system, where it ensures a firm and reliable attachment of the tube without any play.

Main features

• 🔩 G 1/8" thread – compatible with most hotends (e.g., types V5, V6, J-Head, Creality, Anycubic, Prusa, etc.)
• 🔒 Inner diameter 4 mm – for standard PTFE tubes (Bowden 2×4 mm)
• 🚫 Non-through version – the PTFE tube does not pass through the entire connector, it ends inside
• 🧱 Secure and firm attachment – prevents movement or loosening of the tube during printing
• ⚙️ Easy installation and removal – using a quick-release system
