Tube:Color: BlueLength: 3m (1.5m/Pcs)Inside Diameter: 2mm
Outside Diameter: 4mmFeature:Smooth surface, Non-stick & Corrosion resistance.Environmentally friendly and pollution-free & Durable.Self-lubricating: can convey materials smoothly with the smallest friction coefficient.High&low temperature resistance: usable temperature -190℃~260℃, almost unaffected by temperature.An extremely precise internal diameter can reduce the \"wiggle room,\" or buckling, inside the tube, allowing you to print flexible filaments even on the longest Bowden systems.Fittings:1.PC4-M6 fittingInner diameter(blue end): 4mmThread: 6 mmMaterial: copper and plastic2.PC4-M10 fittingInner diameter(black end): 4mmThread: 10 mmMaterial: stainless steel and plasticUse:
Install: connecting by the outer thread of the quick fitting.
Remove: press and hold the blue or black end of the quick fitting and pull out the tube.Advantage:The upper part can be inserted outer diameter 4mm PTFE tube and self-locking.2 end connections of quick fittings are able to bear greater and stronger impulse but won\'t come off.
Compatibility: fit for 3D Printer 1.75mm Filament and other devices.
