SUNLU PTFE Teflon Tubes for Filament Connector
The SUNLU PTFE (Teflon) Tubes are specialized consumables designed for the SUNLU FC01 Filament Connector. These heat-resistant tubes act as the "mold" and guiding channel where the two filament ends meet and fuse. They ensure the splice remains perfectly straight and prevent the molten plastic from sticking to the heating element. As these tubes undergo wear due to repeated thermal cycles, they are essential replacements for maintaining high-quality filament welds.
High Temperature Resistance: Crafted from premium PTFE material that withstands temperatures up to and beyond without deforming or bonding to the filament.
Ultra-Low Friction: The smooth Teflon interior provides minimal resistance, ensuring the fused filament can be removed easily and flows smoothly through the extruder later.
Precision Inner Diameter: Specifically calibrated for mm filaments to prevent "bulging" or diameter irregularities at the splicing point.
Chemical Inertness: Non-reactive with various 3D printing materials (PLA, ABS, PETG, etc.), ensuring a clean and uncontaminated bond every time.
Durability: A flexible yet wear-resistant design capable of enduring multiple splicing cycles before requiring replacement.
