Features Good Compatibility: Compatible with PLA ABS 1.75mm 3D printer, the compatibility is very good. Tight tolerances ensure that the filament leads directly to the hot end with as little margin of error as possible between the extruder and the hot end. Convenience: The pneumatic joint supports 360° rotation and can be freely disassembled, bringing you more convenience. Less friction means more responsiveness, less retraction, more accurate printing, less slippage, less extruder wear and tear, and when printing thick filaments (such as some wood). filler or iron filler) less clogging. Heat Resistance: The PTFE tube is made of PTFE material, and the heat resistance can reach 260 degrees. Ideal for printing special filaments such as ABS, nylon and polycarbonate. Suitable for: Suitable for Creality Ender 3 with wide applicability. The pneumatic fittings in the kit are used to hold the PTFE in the extruder and hot end. Easy to Install: Well-crafted to provide exceptional quality, with well-crafted details to better suit your needs. Compact, lightweight and easy to install. Small 3D printer accessories, please keep away from children.
