Blue Collet Clip for 3D Printer Pneumatic Coupler PC4-M6 PC4-M10

The Blue Collet Clip (also known as the Bowden tube clip or pneumatic coupler buckle) is a small but critical accessory for maintaining high-quality prints on your FDM 3D printer. This clip is designed to slide under the plastic collet of standard PC4-M6 and PC4-M10 pneumatic fittings. By locking the collet in its extended position, it prevents the PTFE Bowden tube from sliding or wobbling during rapid retraction cycles, directly solving common issues like under-extrusion, stringing, and filament clogging.

This lightweight plastic buckle is highly compatible with popular 3D printers such as the Creality Ender series, CR-10, Anycubic, and custom DIY RepRap builds. It is an essential spare part for makers, students, and engineers who want to optimize their extruder and hotend setups for maximum precision and reliability. Easy to install and remove, it ensures a tight, play-free connection between your extruder and the PTFE guide tube.

Note: This package includes only the blue plastic clip. The metal pneumatic connector is shown for illustration purposes only and is sold separately.

Features:

• Eliminates Tube Play: Securely locks the pneumatic coupler's collet to prevent PTFE tube movement during retraction.
• Improves Print Quality: Minimizes stringing, oozing, and extrusion inconsistencies caused by loose Bowden tubes.
• Universal Compatibility: Fits standard PC4-M6, PC4-M10, and similar pneumatic quick-connect fittings.
• Ultra-Lightweight Design: Weighs only 0.1 grams, adding zero bulk to your printer assembly.
• Durable Construction: Made from high-quality, flexible plastic that resists wear and tear over long printing hours.
• Tool-Free Installation: Easily snaps into place under the collet collar in seconds.
